Use a o = 0.05 significance level to test the claim that o = 16 if the sample statistics include n = 13, x = 98, and s = 21. The test statistic is The smaller critical number is The bigger critical number is What is your conclusion? O A. There is not sufficient evidence to warrant the rejection of the claim that the population standard deviation is equal to 16 O B. There is sufficient evidence to warrant the rejection of the claim that the population standard deviation is equal to 16
