Question

monthly sale of beer at a bar is believed to be approximately normally distributed with mean 2450 units and standard 400 units.to determine the level of orders and stock ,the management wants to find two value symmetrically on either side of mean,such that the probability that sales of beer during the month will be between the two values is 0.95 and 0.99 find the required value

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.
