3. The data file gives the location and total points earned per game for the Denver Nuggets, for the first 50 games of the 2021-2022 Season. The Location variable identifies if the game was at home or away. There were 23 home games with a mean of 110.8 and standard deviation of 13.0, and there were 27 away games with a mean of 104.7 and standard deviation of 11.9. Let ph-mean points at home and MA = mean points at away games. Can we conclude the Denver Nuggets earn more points when they play at home using a = .05?

Conclusion: 4. Eighty-six patients with bladder cancer participated in a study in which all tumors were removed and then the subjects were monitored to see if the tumors returned. Patients were randomly assigned to one of two treatment groups: one group received a placebo, and one group received the drug thiotepa Tumors returned in 29 out of 48 patients in the placebo group and in 18 out of 38 patients in the thiotepa group. (6 points) a) Find and interpret a 90% confidence interval for the difference in the proportion of tumors returning between the two treatments. b) Using the confidence interval, is it plausible that the drug appears to be more effective than the placebo in preventing tumor regrowth? Explain why or why not.
