Question

A sample of 415 people is selected. The people are classified according to place of residence (^ * urban^ * , "suburban", or "rural"). They are also classified according to highest educational degree earned ("no college degree", "two-year degree", "four-year degree", or "advanced degree"). The results are given in the contingency table below.

Answer 1

.The total number of people with two year degree is given by:

`45+48+23=116`

The total number of people is 415.

Therefore, the required relative frequency is 116/415

`(116)/(415)=0.28`

Therefore, the required relative frequency is 0.28
