Question

Use the t-distribution and the sample results to complete the test of the hypotheses. Use a 5 % significance level. Assume the results come from a random sample, and if the sample size is small, assume the underlying distribution is relatively normal. Test H0 : ? = 15 vs Ha : ? > 15 using the sample results x? = 17.2, s = 6.4, with n = 40. (a) Give the test statistic and the p-value. Round your answer for the test statistic to two decimal places and your answer for the p-value to three decimal places. test statistic = p-value = (b) What is the conclusion? Reject H0. Do not reject H0.

(a) Give the test statistic and the p-value.

Round your answer for the test statistic to two decimal places and your answer for the p-value to three decimal places.

test statistic = 

p-value = 

(b) What is the conclusion?

Reject H0.
Do not reject H0.
