Question
Consider the following hypothesis test.
Ho: H = 15
H: 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.)
(b) Find the p-value. (Round your answer to four decimal places.)
p-value =
(c) At a = 0.05, state your conclusion.
O Reject Ho. There is sufficient evidence to conclude that u + 15.
O Reject Ho. There is insufficient evidence to conclude that u + 15.
O Do not reject Ho. There is sufficient evidence to conclude that u + 15.
O Do not reject Ho. 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.)
test statistic <
test statistic 2
State your conclusion.
O Reject H. There is sufficient evidence to conclude that µ # 15.
O Reject Ho. There is insufficient evidence to conclude that u + 15.
O Do not reject Ho. There is sufficient evidence to conclude that u + 15.
O Do not reject Ho. There is insufficient evidence to conclude that u + 15.
