For each of the following samples that were given an experimental treatment, test whether these samples represent populations that are different from the general population: (a) a sample of 10 with a mean of 44, (b) a sample of 1 with a mean of 48. The general population of individuals has a sample of 40, a standad deviation of 6, and follows a normal curve. For each sample, carry out a Z test using the five steps hypothesis testing with a two tailed test at the .05 signifigance level
