Essay

In a manufacturing production process, two machines are being compared. The data below show the diameters, measured in millimeters, of a sample of ball bearings produced by each machine. $$\begin{array} { l l } \text { Machine A } & \text { Machine B } \\1.95 & 2.22 \\2.45 & 2.30 \\2.50 & 2.34 \\2.75 & 2.28 \\2.38 & 2.29 \\2.26 & 2.25 \\2.33 & 2.30 \\2.20 & 2.27 \\2.16 & 2.38 \\2.20 & 2.34\end{array}$$ Use Excel to determine whether the variance in diameters differs between the two machines. Use a .05 level of significance.
