Do you reject H₀ at the $\alpha = 0.01$ level?

Question

The following output from MINITAB presents the results of a hypothesis test. Test of mu

= 49 \mathrm { vs }

. not

= 49

The assumed standard deviation

10.4

\begin{array}{lcccrr}\mathrm{N} & \text { Mean } & \text { SE Mean } & 95 \% \mathrm{CI} & \mathrm{Z} & \mathrm{P} \\58 & 46.32 & 1.412088 & (43.5523077,49.0876923) & -1.962526 & 0.049701 \\\hline\end{array}

Do you reject H₀ at the

\alpha = 0.01

level?

Quizplus · Accepted Answer

The p-value of 0.049701 is greater than the alpha level of 0.01, so we do not reject the null hypothesis at the 0.01 significance level.
