Question

One measure of the health of a nation’s economy is how quickly it creates jobs. One aspect of this issue is the number of jobs individual holds. As part of a study on job tenure, a survey was conducted wherein Americans aged between 37 and 45 were asked how many jobs they have held in their life time. Also recorded were gender and education attainment. The categories are:

Less than high school (E1)

High school (E2)

Some college/University but no degree (E3)

At least one university degree (E4).

The data are shown for each of the eight categories of gender and education.

Can we infer that any difference exists between genders and education levels in terms of the number of jobs? In other words, does gender or education level significantly affect the number of jobs?
