[Step-by-Step] A random sample of 51 observations was selected from a normally distributed population. The sample mean was x̄ = 88.6, and the sample variance
Question: A random sample of 51 observations was selected from a normally distributed population. The sample mean was \[\bar{x}\] = 88.6, and the sample variance was s 2 = 38.2. Does the sample show sufficient reason to conclude that the population standard deviation is not equal to 8 at the 0.05 level of significance? Use the p -value method.
