Question

a sample of 435 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.
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: Find number of rural - residents

Add up the number of rural - residents in each educational degree category.
$38 + 44+44 + 47=173$

Step2: Calculate relative frequency

Relative frequency = $\frac{\text{Number of rural - residents}}{\text{Total number of people in sample}}$.
The total number of people in the sample is 435. So, relative frequency = $\frac{173}{435}\approx0.40$

Answer:

$0.40$
