Question

In a random sample of 750 toner cartridges, the mean number of a toner cartridge can print is 4302 and the standard deviation is 340. Assume the distribution of data is normally distributed

The company that makes the toner cartridges guarantees to replace any cartridge that prints fewer than 3282. Approximately how many of the cartridges in the sample would you expect to be replaced under the guarantee policy?

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.
