Women drivers
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 value of the test statistic?
