For the Following Hypothesis Test: with N = 15,s

question 45

Multiple Choice

For the following hypothesis test: With n = 15,s = 7.5,and = 62.2,state the decision rule in terms of the critical value of the test statistic

• 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.
