The American Housing Survey reported the following data on the number of times that owner-occupied and renter-occupied units had a water supply stoppage lasting 6 or more hours in the past 3 months. Number of Houses (1000s) Number of Times Owner Occupied Renter Occupied 0 549 23 1 5,012 542 2 6,100 3,734 3 2,544 8,690 4 times or more 558 3,783 Do not round intermediate calculations. Round your answers to two decimal places. a. Define a random variable x = number of times that owner-occupied units had a water supply stoppage lasting 6 or more hours in the past 3 months and develop a probability distribution for the random variable. (Let x = 4 represent 4 or more times.) x f(x) 0 1 2 3 4 Total b. Compute the expected value and variance for x. Total E(x) Var(x) c. Define a random variable y = number of times that renter-occupied units had a water supply stoppage lasting 6 or more hours in the past 3 months and develop a probability distribution for the random variable. (Let y = 4 represent 4 or more times.) y f(y) 0 1 2 3 4 Total d. Compute the expected value and variance for y. Total E(y) Var(y) e. What observations can you make from a comparison of the number of water supply stoppages reported by owner-occupied units versus renter-occupied units? The number of times of water supply stoppages in owner-occupied houses is than in renter-occupied houses, and the variability in the number of times is for the owner-occupied houses
