v Managers of an outdoor coffee stand in Coast City are examing the relationship between (hot) coffee sales and daily temperature, hoping to be able to predict a day's total coffee sales from the maximum temperature that day. The biyariate data values for the coffee sales {denoted by y, in dollars) and the maximum temperature {denoted by x, in degrees Fahrenheit) for each of fteen randomly selected days during the past year are given below. These data are plotted in the scatter p in Figure 1. Temperature.- X {in degrees Fahrenheit] 45.5 38.5 Law-. [Zin dollars] t 51.1 3?.9 . We 1' x 315.1 x 314.3 314.9 . "WT " 53.1 . A.\" 1'03 81.? 33w.
