Give the rejection region and not the Pvalue 5 74 A minitab

Give the rejection region and not the P-value.

5 - 74 A minitab ANOVA output is shown below. Fill in the Blanks.

Solution

Critical region for each different alpha. We use excel function finv(alpha , 3,16)

At 0.05 the rejection region is given by F>3.239

Since calculated value does not lie in rejection region we fail to reject Ho
