Question: A random sample of 51 observations was selected from a normally distributed population. The sample mean was xbar = 22, and the sample variance was s2 = 11.0. Does the sample show sufficient reason to conclude that the population standard deviation is not equal to 5 at the 0.02 level of significance? Use the p-value method.
