4. Do a majority of Minnesotans prefer green bean hotdish? A recent poll of 400 ran-
domly selected Minnesotans hopes to answer this very important question. In the poll
190/400 = 47.5% of respondents answered that green bean hotdish is their favorite
hotdish, while the remaining Minnesotans in the poll preferred a different hotdish.
(a) Consider the distribution of all Minnesotans' preference for green bean hot dish
versus any other kind of hot dish. Explain why the standard deviation of this
distribution is bounded by 1/2.
(b) Find a 95% confidence interval for the proportion of all Minnesotans who prefer
green bean hotdish.
(c) Interpret your 95% confidence interval.
(d) Interpret the 95% confidence level.

## In a survey of adults with diabetes, the average body mass index (BMI) in a sample of 1938 women was 32.2 with a standard deviation of 0.03. The BMI in a sample of 1555 men was 30.4, with a standard deviation of 0.06. Construct a 92% confidence interval for the difference in the mean BMI between women and men with diabetes, INTERPRET THE RESULTS. DOES THE CONFIDENCE INTERVAL CONTRADICT THE CLAIM THAT THE MEAN BMI IS THE SAME FOR BOTH MEN AND WOMEN WITH DIABETES?

Do AP Statistics students have higher GPA's than non AP Statistics students? Random samples of 20 AP Statistics students and 20 non AP Statistic students were taken. AP Statistics students had a mean GPA of 3.335 with a standard deviation of 0.557. Non AP Statistics students had a mean GPA of 3.04 with a standard deviation of 0.685. Assume the distribution of all AP Statistics scores are normally distributed. Use a 95% confidence interval for the true difference in average GPAS for AP Statistics and non AP Statistics students to determine if one group has a higher GPA than the other.
