Question

A major credit card company has determined that the amount its customers charge on their accounts is normally distributed with an average of 2800 per month and a standard deviation of 200.

If the company has 20 000 customers, how many customers charge less than 2430 per month round off to zero decimals

Six sprinters have made it to the Olympic finals in the 100 meter race. In how many different ways can the gold, silver and bronze medals be awarded. Rounded off to zero decimals

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.
