Just need help with (d)

Consider the following hypothesis test.
Ho: H = 15
H3: u = 15
A sample of 50 provided a sample mean of 14.09. The population standard deviation is 3.
(a) Find the value of the test statistic. (Round your answer to two decimal places.)
-2.14
(b) Find the p-value. (Round your answer to four decimal places.)
p-value = 0.0324
(c) At a = 0.05, state your conclusion.
Reject Ho: There is sufficient evidence to conclude that u * 15.
Reject Ho. There is insufficient evidence to conclude that u = 15.
Do not reject H,. There is sufficient evidence to conclude that u + 15.
Do not reject H,: There is insufficient evidence to conclude that u + 15.
(d) State the critical values for the rejection rule. (Round your answers to two decimal places. If the test is one-tailed, enter
NONE for the unused tail.)
