Assume that the flight time between Cleveland, OH (CLE) and Raleigh, NC (RDU) is uniformly distributed between 60 and 90 minutes Suppose I booked a fight between these two cites. a. What is the probability that my flight will take between 80 and 100 minutes? 15 pts.) b. What is the probability that my flight will take less than 85.5 minutes? 15 pts. What is the probability that my Mielt will more than 70 minutes? (5 pts. d. What is the probability that my night will less than 75 minutes? 15 pts.] e. What is the mean flight time? (5 pts.) 1. What is the variance of the flight time? 5 pts. 8. What is the standard deviation of the fight time? [5 pts Suppose the mean grade for a statistics midterm exam was 70 with a standard deviation of 8. Assume that your grades were normally distributed. [ 40 pts. Totall a what percentage of students received at least an 80? 17.5 pts) b. What percentage of students received an 84? (5 pts.) c. What percentage of students received a grade between 50 and 697|10pts.) d. What percentage of students received a grade less than 707 17.5 pts.) t. 12 students failed the exam ie their grades were less than 60, how many students took the test? Hint; First focus on pix
