a. Use the data given to test the following hypotheses. (Round your answer to 2 decimal places, e.g. 15.25.)
The value of the test statistic is
and we
reject the null hypothesis
b. Use the p-value to obtain the results. (Round your answer to 4 decimal places, e.g. 0.1254.)
Since the p-value of
is
than a = .10, the decision is to:
c. Solve for the critical value required to reject the mean. (Round your answer to 2 decimal places, e.g. 15.25.)
Since the critical x =
is
than the observed x = 1,416, the decision is to:
