Chapter 6, Section 2-HT, Exercise 115

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 : μ=100 vs Ha : μ<100 using the sample results x¯=91.7, s=12.5, with n=30.

(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.
