The line of best fit represents the trend or average relationship between the average study time and quiz grade. It provides an approximation of the expected quiz grade based on the average study time.

To obtain the line of best fit on a scatter plot, you would typically use a method called linear regression. Linear regression aims to find the best-fitting line that minimizes the overall distance between the line and the data points.

Here's a general overview of the steps involved in obtaining the line of best fit:

Plot the scatter plot with average study time on the x-axis and quiz grade on the y-axis.

Visually observe the distribution of the data points. Look for any overall trend or pattern.

Determine the type of relationship between the variables. In this case, we are looking for a linear relationship.

Use a statistical software or calculator that supports linear regression to perform the analysis. This will generate the equation of the line that best fits the data.

The line of best fit is determined by its slope (m) and y-intercept (b), represented by the equation y = mx + b.

The distribution of component size is likely skewed to the right so it is mild positive skewed. so, the correct option is A).  Lower limit for outliers is -279 and upper limit is 1016.

The fact that the largest component (California) has more than three times as many members as the smallest component (Rhode Island) suggests a potentially right-skewed distribution. So, the correct answer is  mild positive skewed and option is A).

To determine the limits for outliers, we need to calculate the lower and upper bounds. Using the interquartile range (IQR) method, we can calculate the lower and upper bounds as:

Lower bound = Q1 - 1.5 x IQR

Upper bound = Q3 + 1.5 x IQR

Where Q1 is the first quartile, Q3 is the third quartile, and IQR is the interquartile range.

Using a calculator or statistical software, we can find:

Q1 = 197

Q3 = 542

IQR = Q3 - Q1 = 345

Substituting these values, we get:

Lower bound = 197 - 1.5 x 345 = -279

Upper bound = 542 + 1.5 x 345 = 1016

Therefore, any component size less than -279 or greater than 1016 would be considered an outlier.

Answer:

8a + 9b and 16a - 10b

Step-by-step explanation:

The median of X is 1;  P(X > 2) = 0; P(one observation < 2 and the other > 2) = P(X < 2) * P(X > 2) = 0 * 0 = 0; Var(X) is approximately 0.33; E(X) is 1 and  the value of q such that P(X < q) = 0.95 is 1.9.

(a) To find the median of X, we need to find the value of x for which the cumulative distribution function (CDF) equals 0.5.

Since the PDF is given as f(x) = 1/2 for 0 < x < 2 and 0 otherwise, the CDF is the integral of the PDF from 0 to x.

For 0 < x < 2, the CDF is:

F(x) = ∫(0 to x) f(t) dt = ∫(0 to x) 1/2 dt = (1/2) * (t) | (0 to x) = (1/2) * x

Setting (1/2) * x = 0.5 and solving for x:

(1/2) * x = 0.5;  x = 1

Therefore, the median of X is 1.

(b) To find P(X > x), we need to calculate the integral of the PDF from x to infinity.

For x > 2, the PDF is 0, so P(X > x) = 0.

Therefore, P(X > 2) = 0.

(c) To find the probability that one observation is less than 2 and the other is greater than 2, we need to consider the possibilities of the first observation being less than 2 and the second observation being greater than 2, and vice versa.

P(one observation < 2 and the other > 2) = P(X < 2 and X > 2)

Since X follows a continuous uniform distribution from 0 to 2, the probability of X being exactly 2 is 0.

Therefore, P(one observation < 2 and the other > 2) = P(X < 2) * P(X > 2) = 0 * 0 = 0.

(d) The variance of X can be calculated using the formula:

Var(X) = E(X²) - [E(X)]²

To find E(X²), we need to calculate the integral of x² * f(x) from 0 to 2:

E(X²) = ∫(0 to 2) x² * (1/2) dx = (1/2) * (x³/3) | (0 to 2) = (1/2) * (8/3) = 4/3

To find E(X), we need to calculate the integral of x * f(x) from 0 to 2:

E(X) = ∫(0 to 2) x * (1/2) dx = (1/2) * (x²/2) | (0 to 2) = (1/2) * 2 = 1

Now we can calculate the variance:

Var(X) = E(X²) - [E(X)]² = 4/3 - (1)² = 4/3 - 1 = 1/3 ≈ 0.33

Therefore, Var(X) is approximately 0.33.

(e) The expected value of X, E(X), is given by:

E(X) = ∫(0 to 2) x * f(x) dx = ∫(0 to 2) x * (1/2) dx = (1/2) * (x²/2) | (0 to 2) = (1/2) * 2 = 1

Therefore, E(X) is 1.

(f) The value of q such that P(X < q) = 0.95 can be found by solving the following equation:

∫(0 to q) f(x) dx = 0.95

Since the PDF is constant at 1/2 for 0 < x < 2, we have:

(1/2) * (x) | (0 to q) = 0.95

(1/2) * q = 0.95

q = 0.95 * 2 = 1.9

Therefore, the value of q such that P(X < q) = 0.95 is 1.9.

The Probability of spinning an odd number both times is \(\dfrac{1}{2}\).

Probability is calculated by the ratio of favourable outcomes and the total number of outcomes.

The total number of outcomes of spinning numbers will be 4 that is 1,2,3,4.

And in which the odd numbers are 1,3.

Therefore the favourable outcome of spinning an odd number both the times will be 2.

Secant can be defined as the reciprocal of cosine. Secant of angle A will be hypotenuse/adjacent.

There are three basic trigonometric ratios. Sin, Cos and Tan.

Sin = opposite side/ hypotenuse

Cos = adjacent side/ hypotenuse

Tan = opposite side/ adjacent side

Here in the give image, Sin(A) = a/c

                                        Cos(A) = b/c

                                        Tan(A) = a/b

There are reciprocals for each trigonometric functions

Cosecant is the reciprocal of sine. Cosec(A) = c/a

Secant is the reciprocal of  Cosine. Sec(A) = c/b

Cotangent is the reciprocal of Tangent . Cot(A) = b/a

If the p-value obtained from the paired t-test is less than the predetermined level of significance (usually 0.05), then it can be concluded that there is a statistically significant difference between the two treatments, and that imitrex is more effective than excedrin at eliminating migraines.

To determine if Imitrex works better than Excedrin at eliminating migraines in your study, the most appropriate statistical test to use is the Paired Samples t-test.

This test is suitable because:
We have two related samples: the same 25 women are given both Excedrin and Imitrex, so their response times are paired.
We're comparing the mean response times between two treatments, which requires a t-test.

The data is assumed to be normally distributed.
To conduct the Paired Samples t-test, follow these steps:
Calculate the difference in response times for each woman (Imitrex time - Excedrin time).

Calculate the mean of these differences.

Calculate the standard deviation of the differences.

Determine the degrees of freedom (25 women - 1 = 24).

Using the mean, standard deviation, and degrees of freedom, calculate the t-statistic.
Compare the t-statistic to the critical value from the t-distribution table, using your chosen significance level (e.g., 0.05).
If the t-statistic is greater than the critical value, reject the null hypothesis, concluding that there's a significant difference between the effectiveness of Imitrex and Excedrin for migraine relief.

To determine if Imitrex works better than Excedrin, the most appropriate statistical test to use would be a "paired t-test."

We are comparing the efficacy of Imitrex and Excedrin for Migraine in the same group of 25 women, with each woman acting as her own control. You are measuring the time it takes for the headache to subside after administering each drug. To determine if Imitrex works better than Excedrin, the most appropriate statistical test to use would be a "paired t-test."

Step-by-step explanation:

1. Record the time it takes for the headache to subside after administering Excedrin and Imitrex to each woman.
2. Calculate the difference in time for each woman between the two drugs.
3. Compute the mean and standard deviation of these differences.
4. Perform a paired t-test to compare the mean difference to 0 (no difference between the two drugs).
5. Assess the p-value obtained from the t-test. If the p-value is less than the significance level (usually 0.05), then you can conclude that there is a statistically significant difference between the two drugs, suggesting that Imitrex works better than Excedrin in eliminating migraines.

B. Translation and C. Rotation are the transformations that can be used to justify that the squares are congruent.

The translation is a rigid transformation that preserves distance and orientation, so if we translate one square to overlap with the other square, the two squares will be congruent.

Rotation is also a rigid transformation that preserves distance and orientation. By rotating one square around the shared side until it matches the orientation of the other square, the two squares will be congruent.

Reflection and dilation do not preserve orientation, so they cannot be used to show that the squares are congruent. And rotating and then dilating would change the size of one of the squares, so this transformation cannot be used to show that the squares are congruent.
