a. Define a random variable x = number of bedrooms in renter-occupied houses and develop a probability distribution for the random variable. (Let x = 4 represent 4 or more bedrooms.)b. Compute the expected value and variance for the number of bedrooms in renter-occupied houses.c. Define a random variable y = number of bedrooms in owner-occupied houses and develop a probability distribution for the random variable. (Let y = 4 represent 4 or more bedrooms.)d. Compute the expected value and variance for the number of bedrooms in owner-occupied houses.e. What observations can you make from a comparison of the number of bedrooms in renter-occupied versus owner-occupiedhomes?
