Question

A university has 30,330 students. In a random sample of 270 students, 18 speak three or more languages. Predict the number of students at the university who speak three or more languages.

Answer 1

2,020 students.

Explanation:

Let x be the numbers of students at university who speak three or more languages.

We have been given that a university has 30,330 students. In a random sample of 270 students, 18 speak three or more languages.

To find the number of students at the university who speak three or more languages, we will use proportions.

`(x)/(30,300)=(18)/(270)`

`(x)/(30,300)*30,300=(18)/(270)*30,300`

`x=(18)/(9)*1,010`

`x=2*1,010`

`x=2,020`

Therefore, 2,020 students at the university who speak three or more languages..
