Question

The operating life on a “Play All Day” video game is normally distributed with a mean of 48 months and a standard deviation of 6 months. The manufacturer will replace any games that malfunction during the guarantee period. (show all work)
How long should the guarantee period run if the manufacturer does not want to replace more than 6% of the games?

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.
