Consider the following hypothesis test.

A sample of 50 provided a sample mean of 19.1. Assume that the sample size is large enough for the Central Limit Theorem to apply. The population standard deviation is 2 . (a) Find the value of the test statistic. (Round your answer to two decimal places) (b) Using a

, state the critical values for the rejection rule. (Round your answer to two decimal places. If the test is one-sided, enter NONE for the unused tail!) The null typothesls will be rejected if: test statistic s

or test statistic :

(b) Find the p-value. (Round your answer to four decimal places)

Using a

state your conclusion.
