Hypothesis test on population mean; 𝛼 = 0.05; one-tailed test (right); 𝑛 = 37; 𝑠 = 5
This corresponds to a right-tailed test, for which a t-test for one mean, with unknown population standard deviation, using the sample standard deviation, will be used.
Based on the information provided, the significance level is and the critical value for a right-tailed test is
The rejection region for this right-tailed test is
The t-statistic is computed as follows:
If the null hypothesis is rejected.
