Question

A survey of needy and disabled youths showed that 48% of those who had no preschool education were arrested or charged with a crime by the time they were 19, whereas only 34% who had preschool education wound up in this category. The survey did not specify what percentage of the youths in the survey had preschool education, so let us take a guess at that and estimate that 14% of them had attended preschool. (Round all answers to the nearest 1%.)

(a) What percentage of the youths arrested or charged with a crime had no preschool education?
%

(b) What would this figure be if 86% of the youths had attended preschool?
%

Explanation / Answer

(a) What percentage of the youths arrested or charged with a crime had no preschool education?

as you can see in the problem text it said that 48% of those who had no preschool education were arrested or charged with a crime by the time they were 19

(b) What would this figure be if 86% of the youths had attended preschool?

this would change by 1 - 0.86 = 0.14

so the  percentage of the youths arrested or charged with a crime had no preschool education will be 14%
