Traffic Coordinator
A traffic coordinator for a community wishes to determine whether or not there is any difference in the average age of female and male drivers involved in rear-end accidents.The hypothesis test is: H 0 : $\mu _ { 1 } = \mu _ { 2 }$ (no difference in mean age)
H 1 : $\mu _ { 1 } \neq \mu _ { 2 }$ (mean age is different)A random sample of males and females involved in rear-end accidents results in the following Minitab summary: $$\begin{array} { l c c c c c c }
& \text { N } & \text { MEAN } & \text { MEDIAN } & \text { TRMEAN } & \text { STDEV } & \text { SEMEAN } \
\text { FEMALES } & 33 & 23.91 & 20.00 & 23.38 & 9.77 & 1.70 \
\text { MALES } & 38 & 28.87 & 28.50 & 28.44 & 9.67 & 1.57
\end{array}$$
-What is the decision rule at the 0.025 level of significance?
