Question

the following two - way table summarizes the marital status and job status for a sample of statistics students.

	married	not married
full - time job	13	17
part - time job	3	13

what percent of unmarried students work? round your answer to the nearest tenth of a percent.

Explanation:

Step1: Find total unmarried students

Unmarried students: No job (11) + Full - time (17) + Part - time (13). So \(11 + 17+13=41\).

Step2: Find unmarried students who work

Unmarried and work: Full - time (17) + Part - time (13). So \(17 + 13 = 30\).

Step3: Calculate the percentage

Percentage \(=\frac{\text{Unmarried and work}}{\text{Total unmarried}}\times100=\frac{30}{41}\times100\approx73.2\) (rounded to nearest tenth).

Answer:

\(73.2\%\)
