Two local hotels, X and Y, rent out rooms nightly. Let X represent the number of rooms hotel X rents out nightly, and let y represent the number of rooms hotel Y rents out nightly. The mean of X is 49, and the mean of Y is 58. Which
answer choice correctly calculates and interprets the mean of the sum, S = X + Y?
O us = 53.5; the hotels can expect to rent out 53.5 rooms, on average, each night.
O
s = 53.5; on one randomly selected night, the total number of rooms rented out will be 53.5.
Hs = 107; the hotels can expect to rent out 107 rooms, on average, each night.
s = 107; on one randomly selected night, the total number of rooms rented out will be 107.
