Problem: Suppose that the average driving time between Knoxville to Atlanta is known to be normally distributed with mean of u = 3.15 hours and standard deviation of a = 0.45 hours 1.
1. Calculate the probability that your driving time from Knoxville to Atlanta is less than 2.5 hours. (Round to 4 decimal places)
2. Calculate the probability that your driving time from Knoxville to Atlanta is greater than 4 hours. (Round to 4 decimal places)
3. Calculate the probability that your driving time from Knoxville to Atlanta is between 3 and 4 hours. (Round to 4 decimal places)
