Question

A milk company unconditionally guarantees that an unopened, properly refrigerated container of its milk will be fresh for 4 days after the date stamped on the carton. The company's data shows that unopened containers remain fresh on average for 6 days, with a standard deviation of 0.43 days. Assume that the length of time milk stays fresh follows a normal distribution. What percent of the milk containers will spoil in fewer than 5 days after the date stamped?

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.
