Suppose a researcher wants to examine the association between the amounts of Fat and Calories in fast-food hamburgers. The data are given below. Complete parts a through 9. Fat(g) 20 31 35 34 4o 36 42 a; Calories 420 600 610 530 620 670 680 D a) Create a scatterplot of Calories vs. Fat. Choose the correct graph below. 0A 03 on on Calories Fat (9) Calories Fat (9) Calories Calories c) Write the equation of the line of regression. _..----.___ Calories = +( ) Fat (Round to two decimal places as needed.) d) Use the residuals plot to explain whether your linear model is appropriate. Choose the correct answer below. O A. The linear model is not appropriate because the residuals plot shows increasing spread. O B. The linearr model is not appropriate because the residuals plot shows an obvious curved pattern. 0 C. The linear model is not appropriate because the residuals plot shows decreasing spread. O D. The linear model is appropriate because the residuals have consistent spread without any obvious outliers or patterns. O E. The linear model is not appropriate because there is at least one obvious outlier in the residuals plot. e) Explain the meaning of the y-intercept of the line. Select the correct choice below and ll in the answer box to complete your choice. (Round to two decimal places as needed.) O A- The y-intercept indicates that every calorie adds gram(s) of fat, on average. O B- The y-intercept means that a tat-tree hamburger has calorie(s), on average. O C- The yintercept means that a zero-calorie hamburger has gram(s) of fat, on average. O D- The yintercept means that every gram of fat adds calorie(s), on average. f) Explain the meaning of the slope of the line. Select the correct choice below and ll in the answer box to complete your choice. (Round to two decimal places as needed.) O A- The slope indicates that every calorie subtracts gram(s) of fat, on average. O B- The slope indicates that every gram of fat adds calorie(s), on average. O C- The slope indicates that every gram of fat subtracts calorie(s), on average. O D- The slope indicates that every calorie adds gram(s) of fat, on average. g) A new burger containing 36 grams of tat is introduced. According to this model, its residual for calories is + 10. How many calories does the burger have? calorie(s) (Round to two decimal piaces as needed.)Step by Step Solution
