1. Assuming homoscedastic errors, test the hypothesis that age affects charitable donations at
the 5% level.
2. Interpret the coefficient on gender interacted with age.
3. How would you test that the difference in giving between men and women is independent of
age? If you can run the test, run it. If you cannot, explain what you need.

Students on an internship program in the US Fish and Wildlife Service wishes to test the nitrogen content on rivers and waterways in the US Midwest states. 36 sample
measurements were taken in various rivers and waterways and the average nitrogen content is found to be in 2.6 grams per milliliter. Find the 95% and 99% confidence
intervals for the mean mercury content. Population standard deviation is 0.3 gram per milliliter.
If the students want the error to be less than 0.05, how large a sample size would be required at 95% confidence? Would the required sample size increase if a higher
degree of confidence is set?
O a. 95% CI: 2.47 < u< 2.73; 99% CI: 2.50 < µ<2.70. Sample size should be 139. Smaller sample size required if the students set the % confidence higher
O b.95% CI: 2.47 < u< 2.73; 99% CI: 2.50 < µ<2.70. Sample size should be 139. Sample size required will increase if the students set the % confidence higher
