A local bank claims that the waiting time for its customers to be served is the lowest in the area. A competitor
bank checks the waiting times at both banks. Use P-values to test the local bankʹs claim. Use $\alpha$ = 0.05. Assume
the two samples are random and independent. $$\begin{array} { cc}
\text {Local Bank}&\text {Competitor Bank}\
\mathrm { n } _ { 1 } = 45 & \mathrm { n } _ { 2 } = 50 \
\overline { \mathrm { x } } 1 = 5.3 \text { minutes } & \overline { \mathrm { x } } 2 = 5.6 \text { minutes } \
\sigma _ { 1 } = 1.1 \text { minutes } & \sigma _ { 2 } = 1.0 \text { minutes }
\end{array}$$
