# Question

With reference to Example 13.2, verify that the P-value corresponding to the observed value of the test statistic is 0.0808.

Example 13.2

Suppose that 100 high-performance tires made by a certain manufacturer lasted on the average 21,819 miles with a standard deviation of 1,295 miles. Test the null hypothesis µ = 22,000 miles against the alternative hypothesis µ < 22,000 miles at the 0.05 level of significance.
