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 of 11 with a mean of 46​, ​(b) a sample of 1 with a mean of 53. The general population of individuals has a mean of 43​, a standard deviation of 7​, 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 .05 significance​ level, and make a drawing of the distributions involved.

Some researchers claim that herbal supplements improve human memory. To test this claim, a researcher selects a sample of n = 25 college students. Each student is given herbal supplements daily for 6 weeks and then all the participants are given a standardized memory test. For the population, scores on the tests are normally distributed with µ = 70 and σ= 20. The sample of n = 25 students had a mean score of M = 80. Can we conclude...
