A. State the null and alternative hypothesis?

B. determine the p-value and interpret its meaning?(round to three decimal places as needed.)

 

A metropolitan transportation authority has set a bus mechanical reliability goal of 3,800 bus miles. Bus mechanical reliability is measured specifically as the number
of bus miles between mechanical road calls. Suppose a sample of 100 buses resulted in a sample mean of 3,875 bus miles and a sample standard deviation of 325
bus miles. Complete parts (a) and (b) below.
a. Is there evidence that the population mean bus miles is more than 3,800 bus miles? (Use a 0.10 level of significance.)
State the null and alternative hypotheses.
