For the following hypothesis test:
A) This is a two-tailed test of the population mean with σ unknown. Therefore, the decision rule is: reject the null hypothesis if the calculated value of the test statistic, t, is less than -2.1448 or greater than 2.1448. Otherwise, do not reject.
B) This is a two-tailed test of the population mean with σ unknown. Therefore, the decision rule is: accept the null hypothesis if the calculated value of the test statistic, t, is less than -2.1448 or greater than 2.1448. Otherwise, do not accept.
C) This is a two-tailed test of the population mean with σ unknown. Therefore, the decision rule is: reject the null hypothesis if the calculated value of the test statistic, t, is less than -1.1828 or greater than 1.1828. Otherwise, do not reject.
D) This is a two-tailed test of the population mean with σ unknown. Therefore, the decision rule is: reject the null hypothesis if the calculated value of the test statistic, t, is less than -1.1828 or greater than 1.1828. Otherwise, do not accept.
