Based on the information above, what is the p-value? A. 46.64% B. 1.00% C. 3.36% D. 96.64% 13. At a 1% level of significance do you accept or re ect the null hypothesis? A. Accept B. Reject 14. At a 5% level of significance do you accept or reject the null hypothesis? A. Accep B. Reject 15. In comparing sample means using the formula on p460 #2 in the textbook more volatile samples (higher sample standard deviations) makes it likely that the null hypothesis will be A. Less; rejected B. More; rejected C. Less; accepted D. More; accepted E. A and D Page 3 7Explanation / Answer
The test statistic t = (80 - 83)/sqrt (5^2/20 + 6^2/25)
= -1.83
DF = (5^2/20 + 6^2/25)^2/((5^2/20)^2/19 + (6^2/25)^2/24) = 43
With 43 degrees of freedom and 1% significance level the critical value is -2.6951
As the test statistic value is not less than the critical value (-2.6951 < -1.83), so the null hypothesis is not rejected.
13) Option-A is the correct answer.
