Question

a sample of 389 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.
table with rows: urban, suburban, rural; columns: no college degree, two-year degree, four-year degree, advanced degree; values: urban: 37, 47, 43, 22; suburban: 18, 41, 20, 15; rural: 30, 26, 44, 46
what is the relative frequency of people in the sample who do not have a college degree?
round your answer to two decimal places.

Explanation:

Step1: Find total no college degree

Sum the number of people with no college degree across all residences.
Urban: 37, Suburban: 18, Rural: 30. So total = \( 37 + 18 + 30 = 85 \).

Step2: Calculate relative frequency

Relative frequency = \( \frac{\text{Total no college degree}}{\text{Total sample size}} \). Total sample size is 389. So \( \frac{85}{389} \approx 0.22 \).

Answer:

0.22
