Question: To test H0: = 15.7 versus H1: 15.7, a simple random sample of size n = 25 is obtained from a population

To test H0: σ = 15.7 versus H1: σ ˃ 15.7, a simple random sample of size n = 25 is obtained from a population that is known to be normally distributed.

(a) If the sample standard deviation is determined to be s = 16.5, compute the test statistic.

(b) Test this hypothesis at the α = 0.1 level of significance.
