Hypotheses and summary sample statistics are given for a test for difference in means using paired data. Assume that the conditions are met and the underlying distribution is approximately normal.

Test H0 : μd=0 vs Ha≠0 when the sample has x¯d=14.4 with sd=12.1 and nd=40.

Find the value of thet-test statistic and then use thet-distribution to find thep-value.

Round your answers to three decimal places.

test statistic =

p-value =

What is the conclusion using a 5% significance level?

a) Reject H0.

b) Do not reject H0.
