Which statement about the use of independent variables in controlled experiments is correct?.

Answers

Answer 1

In a controlled experiment, an independent variable is manipulated to determine its effect on a dependent variable. In this way, researchers can conclude whether a causal relationship exists between the two variables. The statement about the use of independent variables in controlled experiments that is correct is that they are intentionally manipulated to determine the effect on the dependent variable.

Independent variables in controlled experiments An independent variable is the variable that is manipulated by the researcher in a controlled experiment. Its main role is to produce changes in the dependent variable. In this way, the researcher can determine whether the independent variable has a causal effect on the dependent variable. Variables in controlled experiments

There are different types of variables in controlled experiments, including: Independent variable: It is the variable that the researcher manipulates to determine its effect on the dependent variable.

Dependent variable: It is the variable that the researcher measures to determine the impact of the independent variable.

Control variables: These are the variables that the researcher tries to keep constant throughout the experiment to minimize the effect of other factors on the dependent variable.

Extraneous variables: These are the variables that could affect the dependent variable but are not of interest to the researcher.

Cetaceans give birth to a few well-developed calves at well-spaced intervals. They also feed and protect the calves for long periods. This is in sharp contrast to most fishes, in which many eggs are spawned and the parents spend no time feeding and protecting the offspring.

Has this effort paid off in the case of the great whales?

My response to this question: Unfortunately, this strategy has not paid off for great whales. It has made them more vulnerable to the environmental and human forces. For example, the activity of whaling causes devastating effect on their population and they aren't able to recover from this. Another example , great whales low reproductive rate and their parental care strategy hinders their ability to rebound from whaling and other damages to their population.

Answers

The effort of cetaceans, including great whales, to give birth to a few well-developed calves and provide extended parental care has not been successful in ensuring their population's survival.

The vulnerability of great whales to environmental and human factors, such as whaling, has had devastating effects on their population. Their low reproductive rate, coupled with the intensive parental care they provide, hampers their ability to recover from these threats. Despite their efforts to protect and nurture their offspring, the great whales face significant challenges in maintaining their population numbers.

The combination of these factors has made them particularly susceptible to decline and underscores the need for conservation efforts to safeguard their future survival.

Make an educated guess about the Earth’s albedo if there were no
continents on its surface, and assuming the same amount of glacial
cover and clouds as today.

Answers

If there were no continents on the Earth's surface and the same amount of glacial cover and clouds as today, the Earth's albedo would be higher than it is now.

Albedo refers to the percentage of incoming sunlight reflected by a surface or object. The Earth's average albedo is around 30%, which means that 30% of the sunlight that hits the Earth is reflected back into space. The Earth's albedo is influenced by a variety of factors, including the amount of cloud cover, the presence of snow and ice, and the type of surface it has.

The Earth's continents have a significant impact on the planet's albedo. Continents are usually darker than oceans and have a lower albedo. This is because the continents are covered in vegetation, rocks, and soil, which absorb more sunlight than the reflective surface of the ocean. This means that if there were no continents on the Earth's surface, the planet's albedo would be higher, as the darker land masses would be replaced with lighter ocean surfaces.

One of the voting suggest that the political ideology of US adults is fairly evenly divided. A 1960 Student council survey reveals that approximately 36% were Republicans, 34% were Democrats, and 30% were Independents. Additionally, suppose that 70% of Republicans, 18% of Democrats, and 32% of Independents describe their political views as conservative. Suppose a US adult is selected at random. a. What is the probability a randomly selected US adult is an Independent and not conservative? b. What is the probability that a randomly selected US adult identifies as conservative? c. What is the probability that a randomly selected US adult is Democrat or identifies as conservative? d. Suppose a randomly selected US adult identifies as not conservative. What is the probability they are a Republican?

Answers

a.  Independent and not conservative

The given problem provides the following probabilities:

P(R) = 0.36,

P(D) = 0.34,

P(I) = 0.30,

P(C|R) = 0.70,

P(C|D) = 0.18, and

P(C|I) = 0.32.

We can find the probability of a randomly selected US adult being Independent and not conservative by multiplying the probability of being an independent by the probability of not being conservative, given that they are independent.

Using the formula of conditional probability, we can write:

P(I and not C) = P(I) × P(not C | I)

                       = 0.30 × (1 - P(C | I))

                       = 0.30 × (1 - 0.32)

                       = 0.2040

Thus, the probability that a randomly selected US adult is an Independent and not conservative is 0.2040.

b. Conservative

The probability that a randomly selected US adult identifies as conservative can be found by using the Law of Total Probability.

We can write:

P(C) = P(C | R) × P(R) + P(C | D) × P(D) + P(C | I) × P(I)

       = (0.70 × 0.36) + (0.18 × 0.34) + (0.32 × 0.30)

       = 0.2520 + 0.0612 + 0.0960

       = 0.4092

Thus, the probability that a randomly selected US adult identifies as conservative is 0.4092.

c. Democrat or identifies as conservative

To find the probability that a randomly selected US adult is a Democrat or identifies as conservative, we can use the formula for the probability of the union of two events:

P(D or C) = P(D) + P(C) - P(D and C)

We can calculate P(D and C) using the formula of conditional probability:

P(D and C) = P(C | D) × P(D) = 0.18 × 0.34

                  = 0.0612

Therefore, P(D or C) = P(D) + P(C) - P(D and C)

                                 = 0.34 + 0.4092 - 0.0612

                                 = 0.6880

Thus, the probability that a randomly selected US adult is a Democrat or identifies as conservative is 0.6880.

d. Not conservative and Republican

We can use Bayes' Theorem to find the probability that a randomly selected US adult is a Republican, given that they are not conservative. We know that:

P(R) = 0.36,

P(D) = 0.34,

P(I) = 0.30,

P(C|R) = 0.70,

P(C|D) = 0.18,

P(C|I) = 0.32, and

P(not C|R) = 1 - P(C|R)

                 = 1 - 0.70

                 = 0.30.

We can use Bayes' Theorem to get the following formula:

P(R | not C) = (P(not C | R) × P(R)) / P(not C)

We can calculate P(not C) using the formula of the Law of Total Probability:

P(not C) = P(not C | R) × P(R) + P(not C | D) × P(D) + P(not C | I) × P(I)

             = (0.30 × 0.36) + (0.82 × 0.34) + (0.68 × 0.30)

              = 0.1080 + 0.2776 + 0.2040

              = 0.5896

Substituting these values in Bayes' Theorem, we get:

P(R | not C) = (P(not C | R) × P(R)) / P(not C)

                   = (0.30 × 0.36) / 0.5896

                   = 0.1837

Therefore, the probability that a randomly selected US adult identifies as not conservative and Republican is 0.1837.

when good things happen to someone, the probability of repeating the behavior that occurred before the good things increases. THis best illustrates

Answers

The statement, "When good things happen to someone, the probability of repeating the behavior that occurred before the good things increases" best illustrates the concept of Operant Conditioning.

What is Operant Conditioning?

Operant conditioning is a type of learning process where a person learns to repeat a behavior that is followed by favorable outcomes or to avoid behaviors that result in unfavorable outcomes.Operant conditioning can be summarized using a four-term contingency; a behavior is followed by a consequence, and the nature of the consequence modifies the future occurrence and frequency of that behavior.

Operant conditioning can be understood in terms of antecedents (stimuli that precede a behavior), behavior itself, and consequences (the outcomes that follow a behavior).

For instance, if a person receives a reward (reinforcement) after displaying a certain behavior, the likelihood of that person displaying the same behavior again in the future increases. However, if a person is punished after displaying a particular behavior, the likelihood of the person displaying that behavior again in the future decreases.

In conclusion, when good things happen to someone, the probability of repeating the behavior that occurred before the good things increases, which best illustrates Operant Conditioning.

She keeps a journal for several days noting the amount of time she spends doing the following activities: working: 6 hours a day, attending classes: 3 hours a day, tv watching: 1 hour a day, studying: 1 ½ hours a day. According to the Premack Principle, could Roberta use tv watching as an effective reinforcer for studying? Why not? Roberta reports not enjoying work. Could work be used as an effective reinforcer for studying? Explain.

Answers

The Premack Principle states that a higher-probability behavior can be used as a reinforcer for a lower-probability behavior.

In this case, Roberta wants to increase the time she spends studying, and therefore needs to identify a higher-probability behavior that she can use as a reinforcer.

However, TV watching is not a good choice as a reinforcer for studying because it is already a highly preferred activity for her.

Using a preferred activity as a reinforcer can sometimes result in the opposite effect, as the individual may prioritize the preferred activity over the target behavior (studying in this case).

Regarding work, as Roberta reports not enjoying it, it is less likely to be an effective reinforcer for studying.

The Premack Principle works by identifying behaviors that are already highly preferred, and that can act as motivators for engaging in less preferred behaviors.

If work is not a highly preferred behavior for Roberta, it is less likely to motivate her to increase the time spent studying. A more effective reinforcer for studying could be a preferred activity that is less preferred than TV watching, such as listening to music or going for a walk.
