Question

Top quality 15% of the production is good quality, the worst 15% is bad quality, the rest are medium quality It is defined as. It is known that the production shows normal distribution with average and variance of 100. According to this; a) Below which yield level is poor quality valid? b) What yield levels is medium quality in? c) What level of efficiency is good quality called above?

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.
