Suppose sales at the local pet store are normally distributed and the average sale for each customer is $110.00 with a standard deviation of $15.00. Suppose 250 customers visit the store. Round probability answers to 4 decimal places, i.e. .XXXX DO NOT enter as a percent. DO NOT enter dollar sign. What is the probability the sale for a randomly selected customer is below $94.00?

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.
