The sampling distribution of the sample proportion of your friends who will find employment in the first round of a job search will have a mean of 0.60 (60%) and a standard deviation of 0.071 (7.1%).

A sampling distribution is a probability distribution of a statistic obtained from a larger number of samples drawn from the same population.

The following are the characteristics of the sampling distribution:

The sampling distribution of the sample proportion of your friends who will find employment in the first round of a job search can be interpreted as follows:

Only 60% of the students in a graduating class of 250 will find employment in the first round of a job search. Suppose we take a sample of 20 friends who have recently graduated. Since it is a random sample, it is possible to obtain different values of the sample proportion of your friends who will find employment in the first round of a job search. The distribution of all the possible sample proportions is called the sampling distribution.

The mean of the sampling distribution is equal to the population proportion of 60%. The standard deviation of the sampling distribution can be determined using the formula:

standard deviation = √(p(1-p)/n),

Where p is the population proportion, and n is the sample size.

Standard deviation = √(0.60 x 0.40/20) ⇒ 0.012 (1.2%)

Therefore, the sampling distribution of the sample proportion of your friends who will find employment in the first round of a job search will have a mean of 0.60 (60%) and a standard deviation of 0.012 (1.2%).

The average daily float for the BBC Corporation, based on receiving 30 checks totaling $250,000 with an average delay of five days, is $41,667.

To calculate the average daily float, we need to determine the total amount of funds in transit and divide it by the average number of days the funds are delayed.

In this case, the BBC Corporation receives 30 checks totaling $250,000 in a typical month. The average delay for these checks is five days.

To calculate the total amount of funds in transit, we multiply the average daily amount by the average delay:

Total funds in transit = Average daily amount × Average delay

= ($250,000 / 30 days) × 5 days

= $8,333.33 × 5

= $41,666.67

Rounding to the nearest whole number, the average daily float is $41,667.

Based on the given options, option b (n = 15 and SS = 190 for both samples) is the least likely to reject the null hypothesis in a test with the independent-measures t statistic.

We need to take into account the sample size (n) and the sum of squares (SS) for both samples in order to determine which set of data is least likely to reject the null hypothesis in a test using the independent-measures t statistic.

As a general rule, bigger example sizes will more often than not give more dependable evaluations of populace boundaries, coming about in smaller certainty stretches and lower standard blunders. In a similar vein, values of the sum of squares that are higher reveal a greater degree of data variability, which can result in higher standard errors and estimates that are less precise.

Given the choices:

a. n = 30 and SS = 190 for both samples; b. n = 15 and SS = 190 for both samples; c. n = 30 and SS = 375 for both samples; d. n = 15 and SS = 375 for both samples. Comparing options a and b, we can see that both samples have the same sum of squares; however, option a has a larger sample size (n = 30) than option b does ( Subsequently, choice an is bound to dismiss the invalid speculation.

The sample sizes of option c and d are identical, but option d has a larger sum of squares (SS = 375) than option c (SS = 190). In this way, choice d is bound to dismiss the invalid speculation.

In a test using the independent-measures t statistic, therefore, option b (n = 15 and SS = 190 for both samples) has the lowest probability of rejecting the null hypothesis.

The parametric equations for the line segment joining points P(1, 2, 0) and Q(1, 3, -1) are: x(t) = 1, y(t) = 2 + t, z(t) = -t.

To parametrize the line segment joining the points P(1, 2, 0) and Q(1, 3, -1), we can express the coordinates of points on the line segment as functions of a parameter, typically denoted by t. Let's define the position vector r(t) = (x(t), y(t), z(t)) as the vector that represents a point on the line segment. The parameter t will vary between 0 and 1, where t = 0 corresponds to point P and t = 1 corresponds to point Q. We can find the position vector r(t) by considering the vector equation of the line segment: r(t) = P + t(Q - P). Substituting the given coordinates of points P and Q: r(t) = (1, 2, 0) + t((1, 3, -1) - (1, 2, 0)). Simplifying: r(t) = (1, 2, 0) + t(0, 1, -1). Breaking it down into its components: x(t) = 1 + 0t = 1, y(t) = 2 + 1t = 2 + t, z(t) = 0 - 1t = -t. Therefore, the parametric equations for the line segment joining points P(1, 2, 0) and Q(1, 3, -1) are: x(t) = 1, y(t) = 2 + t, z(t) = -t. These equations describe all points on the line segment as the parameter t varies from 0 to 1.

Answer:

x = 60°

Step-by-step explanation:

See picture below.  When two parallel lines are cut by a transversal there are some special relationships.

Answer:

x = 60°

Step-by-step explanation:

∠ ABO and ∠ CBO are a linear pair and sum to 180° , that is

∠ ABO + ∠ CBO = 180°

150° + ∠ CBO = 180° ( subtract 150° from both sides )

∠ CBO = 30°

∠ XYO and ∠ CBO are alternate angles and are congruent , so

∠ XYO = 30°

∠ XOY and ∠ COY are a linear pair and sum to 180° , then

∠ XOY + ∠ COY = 180°

∠ XOY + 90° = 180° ( subtract 90° from both sides )

∠ XOY = 90°

the sum of the 3 angles in Δ XOY = 180° , that is

x + 90° + 30° = 180°

x + 120° = 180° ( subtract 120° from both sides )

x = 60°

The probability that more boys than girls are chosen is 0.4590

as we know,

Probability of any event P(E) = \(\frac{Number of favorable outcomes}{Total number of outcomes}\)

We have to chose five students to do presentations and also number of boys must be greater than the girls.

In classroom there are 12 boys and 13 girls.

So, Possible arrangements can be: B - Boys, G - Girls

(3B, 2G) , (4B, 1G) , (5B, 0G).

Note: nCr = n! / ( (r!) x (n-r)! ) also see the attached figure.

To choose 5 students out of 25 students to do the presentation 25 C 5

25 C 5 = 25! / (5! x 20!) = 53,130

(3B, 2G) :

To chose 3 Boys out of 12 Boys 12 C 3 = 12! / (3! x 9!) = 220

To chose 2 Girls out of 13 Girls 13 C 2 = 13! / (2! x 11!) = 78

(4B, 1G) :

To chose 4 Boys out of 12 Boys 12 C 4 = 12! / (4! x 8!) = 495

To chose 1 Girl out of 13 Girls 13 C 1 = 13! / (1! x 12!) = 13

(5B, 0G) :

To chose 5 Boys out of 12 Boys 12 C 5 = 12! / (5! x 7!) = 792

To chose 0 Girl out of 13 Girls 13 C 0 = 13! / (0! x 13!) = 1

here, 0! is equal to 1.

Now, the probability that more boys than girls are chosen =

\(\frac{(220 *78) + (495 * 13) + (792 * 1) }{53,130}\)

P(E) = 0.4590

Hence, the probability that more boys than girls are chosen is 0.4590.
