Exercise 9.1 Solve the following problems and show your complete solutions. Consider a random variable that is normally distributed where ( = 60; 6 = 2, and x = 55. Find the corresponding value of z and interpret its computed value. Based on a survey, the average monthly allowance of the international students of ABC University is Php25,000.00 with a standard deviation of Php 1,000.00. Assuming that the monthly allowance is normally distributed, what is the z-score of an international student with a monthly allowance of (a) Php28,000.00? (b) Php23,000.00? 3. Assuming that the Entrance Test scores of Grade 11 students are normally distributed with a mean of 120 and a standard deviation of 10.
