In the past,young women drivers have maintained a better driving record than young men drivers.An insurance company is concerned with the driving record of its insured customers.Specifically,it conducts a test for the number of speeding tickets received during the past year by drivers between the ages of 18 and 25. $$\begin{array} { | c | c | }
\hline \text { Men } & \text { Women } \
\hline n _ { 1 } = 120 & n _ { 2 } = 85 \
\bar { x } _ { 1 } = 1.2 & \bar { x } _ { 2 } = 0.4 \
s _ { 1 } ^ { 2 } = 24.8 & s _ { 2 } ^ { 2 } = 10.6 \
\hline
\end{array}$$
-A test for the equality of average number of tickets per driver for the two groups is desired.Use $\alpha$ = 0.01.What is the conclusion?
