4. A process runs with a process mean and standard deviation of M = 8.2 and o = 0. 9 and is normally distributed. Determine specification limits that will contain 99% of the population: a. assuming that the process mean and standard deviation never change. b. if shifts in the process mean up to 1o must be tolerated.

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.
