For the following hypothesis: With n = 20, = 71.2,s = 6.9,and α = 0.1,state the decision rule in terms of the critical value of the test statistic.
A)This is a one-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 greater than 1.3277.Otherwise,reject.
B)This is a one-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 greater than 2.1727.Otherwise,reject.
C)This is a one-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 greater than 1.3277.Otherwise,do not reject.
D)This is a one-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 greater than 2.1727.Otherwise,do not reject.
