Transcribed Image Text:You are interested in studying the relationship between class size and test scores. Past research
has suggested that smaller classes lead to better student outcomes. You have decided to test
this hypothesis. To do so, you have collected data on 22 students at SDSU. You have data on
student GPA, and the average class size for the student.
You estimate the following regression:
GPA,= Bo + Bi Class Size + €₁
You get the following results:
bo= 4.000
b₁ = .020
SE = 1.230
SE = 0.010
What is the 99% confidence interval for the slope parameter b₁? Use Table D. Note that the
degrees of freedom will be n-2. Round your answer to the third decimal point.
