Question: Robert Pencil Warren[1], you will remember him from the midterm, has been asked by the Prescott Rural Electric Coop to study the costs of several households in a subdivision, Prescottvilla that they serve. The folks there are concerned that their bills are “Too darn high.” Here are the costs for a recent month at the homes in Prescottvilla along with the number of rooms that each home has.

? Compute range, standard deviation, quartiles, and anything else you can think about and then discuss what old Robert should tell the Coop about the bills in Prescottvilla. Are the bills too high, given what you know about the data?

? If the average customer for the Coop has a monthly bill of $124.56 and has seven (7) rooms, are the people in Prescottvilla paying too much, just about right or too little for their electric service?
