Suppose a random sample of size 22 is taken from a normally distributed population, and the sample mean and variance are calculated to be a = 5.28 and 82 = 0.5respectively. Use this information to test the null hypothesis Ho : / = 5 versus the alternative hypothesis HA : # > 5 . a) What is the value of the test statistic, for testing the null hypothesis that the population mean is equal to 5? Round your response to at least 3 decimal places. Number b) The p-value falls within which one of the following ranges: p-value > 0.10 0.05
