Come from populations with the same mean. Assume that the samples are independent simple random samples. Use a significance level of a = 0.05 Sample 1: n1 = 7, x1 = 20.6, s1 = 7.03 Sample 2: n2 = 16, x2 = 24.5, s2 = 5.1 %3D %3D (a) The degree of freedom is (b) The test statistic is (c) The P-value is (give to 4 decimal places): (d) The final conclusion is OA. There is not sufficient evidence to reject the null hypothesis that (u1 - 42) = 0. OR We can reiect the null hypothesis that (u - µ2) = 0 and accept that (u1 - pu2) # 0.

Question
Please see below. I need help with this.
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 a = 0.05 Sample 1: n1 =7, x1 = 20.6, s1 = 7.03 Sample 2: n2 = 16, x2 = 24.5, s2 = 5.1 (a) The degree of freedom is (b) The test statistic is (c) The P-value is (give to 4 decimal places): (d) The final conclusion is OA. There is not sufficient evidence to reject the null hypothesis that (u1 – 42) = 0. OB. We can reject the null hypothesis that (u1 – µ2) = 0 and accept that (u1 – µ2) # 0.
