In Testing the Difference Between Two Population Means Using Two

question 11

Short Answer

In testing the difference between two population means using two independent samples, the population standard deviations are assumed to be known and the calculated test statistic equals 1.05. If the test is upper-tail and the 10% level of significance has been specified, the conclusion should be to: $\begin{array}{|l|l|}\hline A&\text {reject the null hypothesis. }\\\hline B&\text {not to reject the null hypothesis. }\\\hline C&\text { choose two other independent samples.}\\\hline D&\text {None of these choices are correct. }\\\hline\end{array}$
