Question:
Repeat the exercise in the preceding problem but let Y and X denote the male and female critical reading scores, respectively.
Repeat exercise
Refer to the SAT data given in Exercise 2.16.
In exercise
The following table gives data on mean Scholastic Aptitude Test (SAT) scores for collegebound seniors for 19722007. These data represent the critical reading and mathematics test scores for both male and female students. The writing category was introduced in 2006. Therefore, these data are not included.
Suppose you want to predict the male
math (Y ) scores on the basis of the female math scores (X) by running the following
regression:
Yt = β1 + β2Xt + ut
a. Estimate the preceding model.
b. From the estimated residuals, find out if the normality assumption can be sustained.
c. Now test the hypothesis that β2 = 1, that is, there is a one-to-one correspondence between male and female math scores.
d. Set up the ANOVA table for this problem.
