Question

Customers at the restaurant have to wait an average of 25 minutes before they receive their meal
from the time their order was placed. Assume these waiting times are normally distributed with a
standard deviation of 5 minutes.

Question: What is the maximum waiting time for a customer to receive her meal if she is in the 10% of
customers who receive their meals in the fastest time from when the order was placed?

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.
