A simple random sample of 52 adults is obtained from a normally distributed population, and each person's red blood cell count (in cells per microliter) is measured. The sample mean is 5.25 and the standard deviation is 0.67. Use a 0.08 signicance level to test the claim that the sample is from a population with a mean equal to 5.4, which is a value often used for the upper limit of the range of normal values. What do the results suggest about the sample group? Show all your work on paper. Enter the p-value with 4-decimal places. The standard deviation of math test scores at one high school is 16.1. A teacher claims that the standard deviation of the sophomores' test scores is different to 16.1. A random sample of 20 results in scores are given below. Use a significance level of 2% to test the teacher's claim and use the P-value method. This is the data: 46, 39, 43, 51, 26, 38, 33, 43, 29, 22, 50, 60, 20, 13, 53, 51, 46, 39, 42, 58 Enter the p-value with 4-decimal places
