1. The weight of all male senior high school students from one province is measured and is found to be approximately normally distributed with a mean of 115 lbs. and standard deviation of 3 lbs. Find the percentile rank of the following heights.

a. 112 lbs.
b. 115 lbs.
c. 117 lbs.
d. 120 lbs.

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.
