Out of 1,370 students, 990 are predicted to have a television in their bedroom
How to predict the number of students?
From the complete question, the probability that a student has a television in his bedroom is:
p = 72.23%
Given that the number of students is 1370
The expected number of students that have television is:
E(x) = p * n
This becomes
E(x) = 72.23% * 1370
Evaluate the product
E(x) = 989.5510
Approximate
E(x) = 990
Hence, out of 1,370 students, 990 are expected to have a television in their bedroom
