Assume that the samples are independent simple random samples. Sample 1: 2120, T1 14, s1 3.5. Sample 2: n2 = 9, x2 = 7, s2 = 1. (a) The test statistic is 8.2285 (b) Find the t critical value for a significance level of 0.01 for an alternative hypothesis that the first population has a larger mean (one- sided test): t*- (c) The conclusion is O A. There is sufficient evidence to warrant rejection of the claim that the two populations have the same mean and accept that the first population has a larger mean. B. There is not sufficient evidence to warrant rejection of the claim that the two populations have the same mean. Note: You can earn nartial credit on this oroblem
