QUESTION:

A hypothesis will be used to test that a population mean equals 7 against the alternative that the population mean does not equal 7 with unknown variance. What are the critical values for the test statistic \(T_{0}\) for the following significance levels and sample sizes?
(a) \(\alpha=0.01\) and \(n=20\)
(b) \(\alpha=0.05\) and \(n=12\)
(c) \(\alpha=0.10\) and \(n=15\)
