Question

A university has 29,370 students. In a random sample of 210 students, 14 speak three or more languages. Predict the number of students at the university who speak three or more languages.

Answer 1

ok so out of 210 14 speak 3 or more so that is a ratio of

210:14

so lets find out how many times 210 goes into the whole populaiton

29370/210=139.857142857

then lets multiply the 14 by that amount

14*139.857142857=1958(exact)

so out of the 29370 1958 speak 3 or more launges

Hope This Helps!!!
