The Natural Cereal Company claims that the average weight of is cereal boxes is at least 15oz. If a random sample of 24 boxes produced a sample mean x = 13.8 and a sample standard deviation s = 4.8, use the sample mean and standard deviation to test the claim at the 95% (? = 0.05) significance level. Use the hypothesis H0: μ = 15 and H1: μ < 15 with a one-tail test. Based on the above T score – should you REJECT the null hypothesis H0? (A) YES (B) NO
