Question

ayşe travels often and lately has become lax about giving herself enough time to get to the airport. She leaves home 45 minutes before the last call for her flight will occur. Her travel time from her front door to the airport parking lot is “normally distributed” with a mean of 25 minutes and a standard deviation of 3 minutes. She must then take a shuttle bus to the terminal from the parking lot and go through security screening. The mean time for doing this is 15 minutes, and the standard deviation is 2 minutes; this time also is “normally distributed.” The driving time and the airport time are independent of each other. What is the probability that Ayşe will miss her flight because her total time for getting to the plane is more than 45 minutes?

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.
