Determine the critical value(s)
The critical value(s) is(are)
(Round to four decimal places as needed. Use a comma to separate answers as needed.)
Determine the test statistic, teTAT-
tSTAT =O
(Round to four decimal places as needed.)
State your statistical decision. Choose the correct answer below.
O A. The test rejects the null hypothesis. The data does not provide sufficient evidence
O B. The test does not reject the null hypothesis. The data provide sufficient evidence to conclude that the mean differs from u= 50.
O C. The test rejects the null hypothesis. The data provide sufficient evidence to conclude that the mean differs from u = 50.
O D. The test does not reject the null hypothesis. The data does not provide sufficient evidence to conclude that the mean differs from u= 50.
conclude that the mean differs from u = 50.
