Body Mass Index: In a survey of adults with diabetes, the average body mass index (BMI) in a sample of 1928 women was 31.30 with a standard deviation of 0.3. The BMI in a sample of 1559 men was 30.50, with a standard deviation of 0.6. Part 1 of 2 (a) Construct a 99% confidence interval for the difference in the mean BMI between women and men with diabetes. Let H, denote the mean BMI for women with diabetes. Use the TI-84 calculator and round the answers to two decimal places. A 99% confidence interval for the difference in the mean BMI between women and men with diabetes is Part: 1 / 2 Part 2 of 2 (b) Does the confidence interval contradict the claim that the mean BMI is the same for both men and women with diabetes? The confidence interval (Choose one) this claim.

The manager at a large fitness center keeps track of the amount of time it takes a sample of 65 clients to run a mile. She finds that the mean time to run a mile in this sample is x = 10.4 minutes and the standard deviation is s = 2.1 minutes. Assuming the sample is a simple random sample of all clients at this particular fitness center, find a 95% confidence interval H, the unknown mean running time of all clients from the fitness center. for (Give your answer as an interval in the form (lower limit, upper limit). Use decimal notation. Give the limits to two decimal places.) 95% confidence interval:
