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 =0.02 . Use the conservative estimate for df. Sample 1: n1=8, x1=25.1, s1=7.39 Sample 2: n2=4, x2=22.9, s2=9.74 (a) The degree of freedom is equation editorEquation Editor (b) The test statistic is equation editorEquation Editor (c) The P-value is (give to 4 decimal places): equation editorEquation Editor (d) The final conclusion is A. There is not sufficient evidence to reject the null hypothesis that (12)=0 . B. We can reject the null hypothesis that (12)=0 and accept that (12)0
