Mrs. Trumbower wants to be able to predict the time customers will have to wait for a table based on the number of customers already waiting. She collects data on y = the time a group of customers wait for a table, and x = the number of names already on the waiting list when that group is added to the list. She finds that the relationship is roughly linear, and calculates the least-squares regression line. One group waited 24 minutes when there were 5 names ahead of them on the list. Which expression below represents the residual for this observation? a. 24 - [2.8 3.77(5)] b. 5-[28 3.77(24)] c. [2.8 3.77(5)] 24 d. [2.8 3.77(5)] - 24 e. [2.8 3.77(5)] - 5
