We are interested in determining whether or not the variances of the sales at two small grocery stores are equal. A sample of 16 days of sales at each store indicated the following: $\begin{array} { l l }
\text { Store A } & \text { Store B } \
n _ { 1 } = 16 & n _ { 2 } = 16 \
s _ { 1 } = \$ 125 & s _ { 2 } = \$ 105
\end{array}$ Are the variances of the populations (from which these samples came) equal?
Use α = .05.
