In this post COVID environment, airlines are having to cancel flights due to insufficient number of pilots and pilot fatigue has become a major issue. Federal regulations state that a pilot must have a rest period of at least ten hours before a flight. A pilot’s advocacy group wants to find out how much rest pilots are actually getting before flights. a. The advocacy group asked 75 pilots how many hours of rest they had before their most recent flight, and found that the average rest time for this sample of pilots was 8.9 hours. Construct a 92% confidence interval for the average hours of preflight rest for the population of airline pilots. Assume that the population standard deviation of the preflight rest hours is 1.5 hours. b. How many pilots should be surveyed in this study (i.e. what sample size do you need) in order to estimate the average preflight rest hours within ± 15 minutes with 94% confidence?

Tetrahedral dice. A tetrahedron is a solid figure with four faces, each of which is an equilateral triangle. We can make dice in the shape of tetrahedra and label their faces with the numbers 1 through 4. When such a die is rolled, the number that lands face down on the table is the result. Create a sample space that represents the toss of a tetrahedral die. Create a sample space that represents the toss of a pair of tetrahedral dice.
