For each of the following samples that were given an experimental treatment, test whether the samples represent populations that are different from the general population: (a) a sample of11 with a mean of 50,(b) a sample of 1 with a mean of 55. The general population of individuals has a mean of 44, a standard deviation of 8, and follows a normal curve. For each sample, carry out a Z test using the five steps of hypothesis testing with a two-tailed test at the 0.05 significance level, and make a drawing of the distributions involved. (c) Figure the 95% confidence interval for parts (a) and (b).
