Question 1: A paper manufacturer wishes to check the quality of the papers. Assume that the strength measurements are normally distributed with a mean equal to 19 pounds and standard deviation equal to 3 pounds. a) If we randomly select 13 papers, what is the probability that the average strength is less than 18 pounds per square inch? b) How many percent of papers have strength more than 23 pounds per square inch? c) Find the strength measurements the represents the third quartile?

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.
