Question

Rewrite the problem in a piece of clean bond paper and indicate the shaded area of the normal curve as part of your solution.

1. An examiner wants to find the percentile rank of an examinee whose score is 73 in MMW subject. Assuming that the scores are approximately normally distributed with a population mean of 110 and a standard deviation of 15. What is the percentile rank of the examinee whose score is 73?

Features Features Normal distribution is characterized by two parameters, mean (µ) and standard deviation (σ). When graphed, the mean represents the center of the bell curve and the graph is perfectly symmetric about the center. The mean, median, and mode are all equal for a normal distribution. The standard deviation measures the data's spread from the center. The higher the standard deviation, the more the data is spread out and the flatter the bell curve looks. Variance is another commonly used measure of the spread of the distribution and is equal to the square of the standard deviation.
