Question

a sample of 396 people is selected. the people are classified according to place of residence (\urban\, \suburban\, or
ural\). they are also classified according to highest educational degree earned (
o college degree\, \two - year degree\, \four - year degree\, or \advanced degree\). the results are given in the contingency table below.

	no college degree	two - year degree	four - year degree	advanced degree
suburban	35	28	37	25
rural	30	42	24	46

what is the relative frequency of people in the sample whose place of residence is rural?
round your answer to two decimal places.

Explanation:

Step1: Calculate total number of rural - residents

Add up the number of rural - residents in each educational degree category. $30 + 42+24 + 46=142$.

Step2: Calculate relative frequency

Relative frequency = $\frac{\text{Number of rural - residents}}{\text{Total sample size}}$. The total sample size is 396. So, relative frequency = $\frac{142}{396}\approx0.36$.

Answer:

$0.36$
