(1 point) Test the claim that the two samples described below come from populations with the same mean. Assume that the samples are independent simple random samples. Use a significance level of 0.04. Sample 1: ni = 75, I1 = 12, si = 3. Sample 2: n2 = 78, 22 = 11, S2 = 1.5. The test statistic is The P-Value is The conclusion is A. There is not sufficient evidence to warrant rejection of the claim that the two populations have the same mean. . B. There is sufficient evidence to warrant rejection of the claim that the two populations have the same mean.
