Using the California School data set from your textbook,you run the following regression: = 698.9 - 2.28 STR
n = 420,SER = 9.4
where TestScore is the average test score in the district and STR is the student-teacher ratio.The sample standard deviation of test scores is 19.05,and the sample standard deviation of the student teacher ratio is 1.89.
a.
Find the regression R2 and the correlation coefficient between test scores and the student teacher ratio.
b.
Find the homoskedasticity-only standard error of the slope.
