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
