Question
Consider the following hypothesis test.
Ho: wS 12
Hai p> 12
A sample of 25 provided a sample mean x 14 and a sample standard deviation s-4.27.
(a) Compute the value of the test statistic. (Round your answer to three decimal places.)
(b) Use the t distribution table to compute a range for the p-value.
p-value > 0.200
0.100 < p-value < 0.200
0.050 < p-value < 0.100
o 0.025 < p-value < 0.050
0.010 < p-value < 0.025
p-value < 0.010
(c) At e- 0.05, what is your conclusion?
Do not reject Ho. There is sufficient evidence to conclude that > 12.
Do not reject Ho. There is insufficient evidence to conclude that w> 12.
Reject Ho. There is insuficient evidence to conclude that w> 12.
Reject Ho. There is sufficient evidence to conclude that w > 12.
(d) What is the rejection rule using the critical value? (If the test is one-tailed, enter NONE for the unused tail, Round your answer to three decimal places.)
test statistic s
test statistic 2
What is your conclusion?
Do not reject Ho. There is sufficient evidence to conclude that u> 12.
Do not reject Hg. There is insufficient evidence to conclude that > 12:
Reject Ho There is insufficlent evidence to condude that > 12.
Reject Ho. There is sufficient evidence to conclude that > 12.
