If ? is given and the research hypothesis is known (that is, one- or two-tailed), then the inverse function may be used to find the rejection region. The Excel inverse functions are as follows: =NORMSINV, =TINV, =FINV, and =CHIINV. In Minitab, the dialog boxes for Normal, t, F, and Chi-sq also contain the inverse functions. Suppose the null hypothesis is H ₀: ? = ? ₀ and the alternative hypothesis is H _a: ? ? ? ₀ and ? = 0.05 and the sample is large. Find the rejection region.

6.

Give the Excel command to find if the rejection region is Z ? -2.33.

7.

Give the Minitab pull-down used to perform a single sample test for a population mean for a large sample.
