The admissions officer for a certain college developed the following estimated regression equation relating the final college GPA to the student's SAT mathematics score and high school GPA.
y^ = -1.4 + 0.0235x1 + 0.00486x2
where
x1 = high-school grade point average
x2 = SAT mathematics score
y = final college grade point average.
(a) Interpret the coefficients in this estimated regression equation.
The expected increase in final college grade point average corresponding to a one point increase in high school grade point average is when SAT mathematics score does not change. Similarly, the expected increase in final college grade point average corresponding to a one point increase in the SAT mathematics score is when the high school grade point average does not change.
(b) Predict the final college GPA for a student who has a high-school average of 84 and a score of 540 on the SAT mathematics test. (Round your answer to two decimal places.)

step-by-step explanation:

7.   there are 10 data points in the set.   the middle point is between 5 and 6.   the middle point in the top half is 8   and the middle point in the bottom half is 3. to find the iqr , take point 8 and subtract point 3

mid term   point 8 = 100   point 3 = 88

iqr = 100-88 = 12

final   point 8 = 93   point 3 = 78

iqr = 93 - 78 = 15

the final has the greatest iqr

6.   b - there is a high data value that causes the data set to be asymmetrical for the males: the data for males are high and asymmetrical .   there is an outlier for the males that skews the data

5.   the   iqr is a better measure of spread for the movies and basketball games.   since the basketball game has an outlier, we do not want to use standard deviation for measurement.  

3.   the exam median is much higher than the class median.   the median line is farther to the right on the exams

2.   there is no way to tell what the means are from the box and whisker plots.
