Question

I dont understand thiz?

Answer 1

B: 110 students. See below for why:

Explanation:

We have 62 votes in total `(12+20+16+14=62)`. What percentage of that 62 voted for kickball?

`16/62~~0.258=25.8%`

The reason we do the survey is that we can estimate the preferences of a large population (the 420 students at the high school) by doing a survey over a smaller population (the 62 students who took the questionnaire). And so if roughly `25.8%` of the survey respondents say they like kickball, we apply that to the entire student body:

`420xx25.8%=420xx0.258=108.36`

The answer closest to this figure is B: 110 students.
