Question

Out of the 150 randomly selected people in the mall, 45 of them were students. Compute the sample population. 

Answer 1

Sample population is given by

n= n₀/ [1+ (n₀-1)/N]

Where n is sample population

n₀ population of students

N population selected

n =45/[1+(45-1)/150]

=45/[1+(44/150)]

=45/1.293

=35.
