It is estimated that 80% of people with type 2 diabetes are overweight. You want to do a study on type 2 diabetics. What is the minimum sample size you will need to estimate the true proportion of people with type 2 diabetes who are overweight to be 85% confident with a margin of error of at most 4.63%? (Use a table or SALT.)

Use a 0.01 significance level. Identify the null hypothesis, alternative hypothesis, test statistic, P-value, and conclusion for the test. Assume this is a simple random sample.
A study was done on body temperatures of men and women. The results are shown in the table. Assume that the two samples are independent simple random samples selected from normally distributed populations, and do not assume that the population standard deviations are equal. Complete parts (a) and (b) below. Use a 0.01 significance level for both parts. a. Test the claim that the two samples are from populations with the same mean.
