1. The length of time it takes from gate to gate for a southwest flight from Phoenix to Atlanta is approximately normally distributed with a mean of 3 hours and a standard deviation of 20 minutes. (Hint - convert all times into minutes)
a. What is the probability the trip time will be less than 2 hour and 30 minutes?
b. What is the probability the trip time will be more than 3 hour and 15 minutes?
c. What is the probability the trip time will between 2 hour and 50 minutes and 3 hours and 20 minutes?
d. What is the probability the trip will be less than 3 hours
The solution contains the determination of various probabilities using the Normal distribution.
