Question 4 (3 marks) Suppose that we are interested in the effects of skipping class on college GPA. Using data (GPA1.DTA), we obtain the following estimated model: colGPA - 1.39 + .412 hsGPA + .015 ACT - 083 skipped (.33) (094) 0.011) 0.026) - 141, R? - 234 (1) Using the standard normal approximation, find the 95% confidence interval for BreGPA. (ii) Can you reject the hypothesis Ho: BhoGPA = .4 against the two-sided alternative at the 5% level? (iii)...

14 A government watchdog association claims that 70% of people in the U.S. agree that the government is inefficient and wasteful. A government agency wants to test this claim. In a random sample of 1165 people in the U.S., 746 agreed with that view. At a 95% confidence level, is there enough evidence to reject the association's claim? is. A medical researcher says that at least 25% of U.S. adults are smokers. In...

6. YChapter 11) In a pediatric clinic, a study is carried out to see how effective aspirin is in reducing temperature. Five 4-year-old children suffering from influenza had their temperature taken immediately before and 1 hour before administration of aspirin. Assuming the normality of data, we constructed 99% confidence interval for the mean difference in temperature before/after taking an aspirin. The 99% confidence interval is (-0.75, 3.95). If you perform the hypothesis test, what...
