5) Consider the estimated equation, which can be used to study the effects of skipping class on college GPA: colGPA = 1.39 + .412 hsGPA
5) Consider the estimated equation, which can be used to study the effects of skipping class on college GPA:
colGPA = 1.39 + .412 hsGPA + 0.15 ACT- 0.083 skipped
(0.33)(0.094) (0.011) (0.026)
n = 141, R2 = 0.234
- Using the standard normal approximation, find the 95% confidence interval for hsGPA.
- Can you reject the hypothesis H0: hsGPA = .4 against the two-sided alternative at the 5% level?
- Can you reject the hypothesis H0: hsGPA = 1 against the two-sided alternative at the 5% level?
