Use the Minitab Display to Test the Indicated Claim ANALYSIS OF VARIANCE ITEMS

Use the Minitab display to test the indicated claim. A manager records the production output of three
employees who each work on three different machines for three different days. The sample results are given
below and the Minitab results follow. Employee
$\begin{array} { r r r r r } & \text { I } & 23,27,29 & 30,27,25 & 18,20,22 \\ \text { Machine } \quad \text { II } & 25,26,24 & 24,29,26 & 19,16,14 \\ & \text { III } & 28,25,26 & 25,27,23 & 15,11,17 \end{array}$


ANALYSIS OF VARIANCE ITEMS

$\begin{array} { l r r r } \text { SOURCE } & \text { DF } & \text { SS } & \text { MS } \\ \text { MACHINE } & 2 & 34.67 & 17.33 \\ \text { EMPLOYEE } & 2 & 504.67 & 252.33 \\ \text { INTERACTION } & 4 & 26.67 & 6.67 \\ \text { ERROR } & 18 & 98.00 & 5.44 \\ \text { TOTAL } & 26 & 664.00 & \end{array}$ Assume that the number of items produced is not affected by an interaction between employee and machine. Using a
0.05 significance level, test the claim that the machine has no effect on the number of items produced.
