See below. I need help with the P-value. Note that all my other answers are RIGHT. I can't figure this answer out. Its NOT: 0.1472, 0.210, 0.2187, 2.266, OR 0.000.
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 Sample 2: n2 = 16, x2 = 24.5, s2 = 5.1 = 20.6, s1 = 7.03 (a) The degree of freedom is 6 (b) The test statistic is -1.323 (c) The P-value is (give to 4 decimal places): 0.2187
