Question: A sample of the 40 observations is selected from one population with a population

standard deviation of 5. The sample mean is 102. A sample of 50 observations is

selected from a second population with a population standard deviation of 6. The

sample mean is 99. Conduct the following test of hypothesis using the .05 significance

level.

\[\begin{aligned} {{H}_{0}}:{{\mu }_{1}} = {{\mu }_{2}} \\ {{H}_{A}}:{{\mu }_{1}} \ne {{\mu }_{2}} \\ \end{aligned}\]

Is this a one tailed test or a two tailed test?
