Candy The following data represent the weight (in grams) of various candy bars and the corresponding number of calories. (a) Draw a scatter diagram of the data, treating weight as the independent variable. (b) What type of relation appears to exist between the weight of a candy bar and the number of calories? (c) Select two points and find a linear model that contains the points. (d) Graph the line on the scatter diagram drawn in part (a). (e) Use the linear model to predict the number of calories in a candy bar that weighs 62.3 grams. (f) Interpret the slope of the line found in part (c)

T stat please      An annual championship event is the most widely watched sporting event in a country each year. In recent​ years, there has been a great deal of interest in the ads that appear during the game. These ads vary in length with most lasting 30 seconds or 60 seconds. The accompanying data represent the ad length and ad scores from a recent championship.
