Question: Consider the following hypothesis test

\[\begin{aligned} & {{H}_{0}}:\mu =25 \\ & {{H}_{A}}:\mu \ne 25 \\ \end{aligned}\]

A sample of 80 is used and the population standard deviation is 10. Use \(\alpha =0.05\). Compute the value of the test statistic Z and specify your conclusion for each of the following sample results

x=22.0

x=27.0
