Short Answer

Test Hypotheses Regarding Two Population Standard Deviations
-A local restaurant claims that the variance of waiting time for its patrons to be served is the lowest in the area. A competitor restaurant checks the waiting time at both restaurants. The sample statistics are listed below. Test the local restaurant's hypothesis. Use $\alpha = 0.05$ .
$$\begin{array} { l l } \text { Local Restaurant } & \text { Competitor Restaurant } \\\mathrm { n } _ { 1 } = 41 & \mathrm { n } _ { 2 } = 61 \\\mathrm {~s} _ { 1 } = 1.1 \text { minutes } & \mathrm { s } _ { 2 } = 2 \text { minutes }\end{array}$$
Assume the samples were randomly selected from normal populations.
