Prоf Reа's Exаm Q4: A study fоund thаt the mean height frоm a random sample of 25 adult American women is 64.5 inches with a standard deviation of 2.5 inches and that the mean height from a random sample of 22 adult American men is 70 inches with a standard deviation of 3 inches. Suppose we are interested in estimating the differences in means from independent random samples of adult American women and men. Research has shown that the distributions of adult heights are normal. Describe two mistakes in the following conclusion: The sample means are normal because it’s stated in the problem. Assume there are 42 degrees of freedom and the confidence level is 75%. Describe the error made and how to fix it:
