Testing Hypothesis. Assume a simple rando sample has been selected froma normally distributed population and test the given claim.Use the traditional method or P-value method for testing hypothesis. Identify the null and alternative hypothesis, test statistics, p-value(or range of P-value), critical value(s), and state the final conclusion that address the original claim.
Red Blood Cell Count: A simple random sample of 50 adults is obtained, and each person's red blood cell count (in cells per microliter) is measured. The sample mean is 5.23. The population standard deviation for red blood cell counts is 0.54. Use a 0.01 significance level to test the claim that the sample is from a population with a mean less than 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?
