Mass transit use between shift$-$ and salaried employees ~ Kenpoolmore is a large manufacturing company with

plants in several large metropolitan areas around the United States. In their ongoing effort to assess their

environmental impact, they take a random sample of the salaried and shift$-$work employees at their plant in

Kentucky. They find that in the sample of $200$ salaried employees, $64$ routinely take mass transit to work, while in

the sample of $250$ shift$-$work employees, $104$ routinely take mass transit to work.

The variables transit type and employee type are independent. The observed difference is due to chance.$\_\_$
