Using proportions, it is found that a reasonable estimate of the number of employees who took off 16 or more days last year is:
9n, in which n is the number of employees who took off 16 or more days of vacation last year in the sample.
A proportion is a fraction of a total amount, and the measures are related using a rule of three. Due to this, relations between variables, either direct or inverse proportional, can be built to find the desired measures in the problem.
In this problem, from a sample of 25 employees, n who took off 16 or more days of vacation last year. Hence, out of 225 employees, the estimate is given as follows:
225 x n/25 = 9n.
