Correct option:
0.445
EXPLANATION:
From given scatter plot, we note that as x increases, y increases. As x decreases, y decreases. So,the correlation between x and y is positive. Also we note that the points are quite spread out from the middle line. This indicates that the correlation is not strong. So, the correlation coefficient cannot be greater than 0.5. So, the only option available is 0.445.

Predicting GPA from Verbal SAT score It is possible to use the information in StudentSurvey to fit a linear model to use Verbal SAT score to predict a student's grade point average in college. The regression equation is GPA^=2.03+0.00189⋅VerbalSAT. Click here for the dataset associated with this question. (a) What GPA does the model predict for a student who gets a 510 on the Verbal SAT exam? What GPA is predicted for a student who gets a 650 ? (b)...
SAT scores are normed so that, in any year, the mean of the verbal or math test score should be 500 and the standard deviation 100. Assuming this is true, answer the following question. What percentage of students score above 625 on the math SAT in any given year? Please round to a whole number and do not put the % sign again.
The mean and standard deviation of SAT math exam scores were 527 and 120, respectively, in 2017. Assume that the scores are normally distributed and answer the following questions. a. Find the 30th percentile. b. If your score is 700, what percentage of the students got higher scores than you in 2017? c. What percentage of students got SAT math scores from 400 to 600? d. If your score is 650, what is the percentile of your score?
the national average SAT score (for Verbal and Math) is 1028. Suppose that nothing is known about the shape of the distribution and that the standard deviation is 100. If a random sample of 200 scores were selected and the sample mean were calculated to be 1050, would you be surprised? Explain.
The national average SAT score (for Verbal and Math) is 1028. Suppose that nothing is known about the shape of the distribution and that the standard deviation is 100. If a random sample of 200 scores were selected and the sample mean were calculated to be 1053. Assume that the sample is taken from a large population and the correction factor can be ignored.

QUESTION 3 Math SAT Question 3 The scores of men on the math SAT follow a Normal distribution so do those of women. It is reasonable to assume that the standard deviations of the two sets of scores are equal. Let us (respectively, u2) denote the average math SAT score of men (respectively, women). A random sample of 20 men was selected. The average math SAT score of the men selected was 607.8 with a standard deviation of 48.76. Another...
