51. Movie candy Is there a relationship between the amount of sugar (in grams) and the number of calories in movie-theater candy? Here are the data from a sam- ple of 12 types of candy: Name Butterfinger Minis 45 450 Junior Mints 107 570 M&M'S Milk Duds Peanut M&M'S Raisinets Sugar " (g) Calories 62 44 480 370 79 790 60 420 Name Reese's Pieces Skittles Sour Patch Kids Sugar (g) Calories 61 580 87 450 92 SweeTarts 136 490 680 Twizzlers 59 460 Whoppers 48 350 (a) Sketch a scatterplot of the data using sugar as the explanatory variable. (b) Use technology to calculate the equation of the least i squares regression line for predicting the number of calories based on the amount of sugar. Add the line to the scatterplot from part (a). (c) Explain why the line calculated in part (b) is called the "least-squares" regression line.
