hypothesis will be used to test that a population mean

QUESTION:

A hypothesis will be used to test that a population mean equals 10 against the alternative that the population mean is greater than 10 with unknown variance. What is the critical value for the test statistic \(T_{0}\) for the following significance levels?
(a) \(\alpha=0.01\) and \(n=20\)
(b) \(\alpha=0.05\) and \(n=12\)
(c) \(\alpha=0.10\) and \(n=15\)
