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.
