Consider the following hypothesis test:

H0: µ = 15

Ha: µ ≠ 15

A sample of 50 provided a sample mean of 14.15. The population standard deviation is 3.

Compute the value of the test statistic. (Round to two decimal places).

What is the p-value? (Round to three decimal places)

At α=0.05, what is your conclusion? (Reject the null hypothesis) or (Do not reject the null hypothesis)
