Question

a sample of 388 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 highest degree is a two - year degree? round your answer to two decimal places.

Explanation:

Step1: Calculate total frequency

The total number of people in the sample is \(18 + 36+19 + 45+31 + 33+38+22 + 46+34+35+31=358\).

Step2: Calculate frequency of two - year degree

The number of people with a two - year degree is \(45 + 31+33=109\).

Step3: Calculate relative frequency

The relative frequency is \(\frac{109}{358}\approx0.30\).

Answer:

0.30
