Question

The demand for a product in the next month shows a normal distribution with an average of 1400 units and a standard deviation of 150 units. Accordingly, the sales;
a) What is the probability that it is more than 1400 units?
b) What is the probability of being between 1350 units and 1450 units?

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.
