Question

A researcher performs a hypothesis test to test the claim that among car owners in one town,the mean number of kilometres driven per year is greater than 22,540.Use the provided computer output to draw a conclusion about the number of miles driven at a significance level of 0.01. Test of $\mathrm { H } _ { 0 }$ : ? = 22,540 vs $\mathrm { H } _ { \mathrm { A } }$ : ? > 22,540
N Mean StDev t P-value
26 25,270 6750 2.06 0.025

Quizplus · Accepted Answer

The p-value (0.025) is greater than the significance level (0.01), so we fail to reject the null hypothesis. There is not enough evidence to conclude that the mean number of kilometers driven is greater than 22,540.
