Application of Normal Distribution
1. The average Pag-ibig salary loan for RFS Pharmacy Inc employee is Php 23,000. If
the debt is normally distributed with a standard deviation of Php 2,500. Find the
probability that the employee owes less than Php 18,500.
Given: ave. mean = Php 23,000
1. deviation = Php 2,500
Find: x < Php 18,500
2.)The average age of bank managers is 40 y/o, assume that the variable is normally
distributed. if the standard deviation is 5 years, find the probability that the age of randomly
selected bank managers will be in the range between 35 and 46 years old.
Given: ave. age = 40 years old
std. deviation = 5 years
Find: x is between 35 and 46 years old
P ( 35< z < 46 )= ?
