Question

(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: $n_1 = 78$, $ar{x}_1 = 19$, $s_1 = 3.5$. Sample 2: $n_2 = 69$, $ar{x}_2 = 11$, $s_2 = 3$. 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.
