Problem 3:

Find the range of annual salaries of the top 15% earners, given the same distribution of FCU graduates. In this problem, the situation is reversed. You are given an area under the curve and have to find a specific value of X that would correspond to the annual salary that separates the highest-paid 15% of FCU graduates. In this situation, you have to move backward. First, find the area (A2) =

A1= A2 =

From Z-table: at A2 = Z=

Using the standard score formula: Z = (X- µ) / σ

X = Z σ + µ =

Thus, the highest-paid 15% of recent FCU graduates make PhP_________ and above per year.
