Question

a sample of 453 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 following table.

	urban	suburban	rural
two - year degree	48	30	42
four - year degree	46	39	46
advanced degree	28	48	46

among the people in the sample whose place of residence is suburban, what is the relative frequency of those who do not have a college degree? round your answer to two decimal places.

Explanation:

Step1: Find total number of suburban people

Add up all the suburban - category values: $41 + 30+39 + 48=158$.

Step2: Find number of suburban people with no college degree

The number of suburban people with no college degree is 41.

Step3: Calculate relative frequency

Relative frequency = $\frac{\text{Number of suburban people with no college degree}}{\text{Total number of suburban people}}=\frac{41}{158}\approx0.26$.

Answer:

0.26
