All questions for problems below is related to one sample hypotheses test for the population mean.

a) Give the decision rule for rejecting the null hypotheses for a right tailed test when the significance level is 0.05 and the sample size is 43.

b) Give the decision rule for rejecting the null hypotheses for a left tailed test when the significance level is 0.03 and the sample size is 28.

c) Give the decision rule for rejecting the null hypotheses for a two tailed test when the significance level is 0.02 and the sample size is 86.

d) Give the decision rule for rejecting the null hypotheses for a left tailed test when the significance level is 0.01 and the sample size is 90.
