Question 1 Uniform Probability Distribution (60 – 70 mins)
Delta Airlines quotes a flight time of 2 hours, 5 minutes for its flights from
Cincinnati to Tampa. Suppose we believe that actual flight times are uniformly
distributed between 2 hours and 2 hours, 20 minutes.
1. Give a mathematical expression for the probability density function of flight time and the expected value and variance of the distribution;
2. Create a scatter graph using dynamic process learnt in the previous sessions to show the uniform probability distribution graphically, then answer the below questions:
a. What is the probability that the flight will be no more than 5
minutes late?
b. What is the probability that the flight will be more than 10 minutes late?
c. What is the probability that the flight will be between 4 and 8
minutes late?
d. In a month of 200 flight journeys finished, how many should have arrived 5 minutes or less earlier?
Question 2 Normal Distribution
New York City is the most expensive city in the United States for lodging. The mean hotel room rate is $204 per night (USA Today, April 30, 2012). Assume that room rates are normally distributed with a standard deviation of $55.
