Question

The daily commuter to work for a section of interstate has a mean of 22 minutes and a standard deviation of 2 minutes. In the same community, the mean commute time on a non-interstate route is also normally distributed with a mean of 19.5 minutes and a standard deviation of 4.1 minutes.

Joey uses the interstate section to get to work and his commute takes 25 minutes. Toyanda uses the non-interstate route to get to work and her commute takes 25.5 minutes. With this in mind, whose route is longer relative to the distribution of commute times for the respective routes?

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.
