5. Consider the following estimated equation that is used to study the effect of skipping class on colege GPA: COLGPA- 1.39+412 HSGPA+015 ACT - 083 skipped (011) (.026) (33) (.094) n= 141, R2= 234 (1) Using the standard normal approximation, find the 95% confidence interval for puA (2) Based on the 95% confidence interval you obtained, can you reject the hypothesis H BOPA = 0.4 against the two-sided alternative at the 5% level? (3) Can you reject the hypothesis H: PPA = 0.1 at the 5% level? (4) Can you reject the hypothesis H,: P 0.8 at the 5% level?
