3-3 WileyPLU Module Three Homework Question150f16 -/2.2 E View Policies Current Attempt in Progress Predicting Percent Body Fat This problem uses the dataset BodyFat.which gives the percent of weight made upof body fat for 100 men as well as other variables such as Age. Weightn pounds), Height [in inches)l and circumference [in cm) measurements for the Neck. Chest,Abdomen, Ankle, Biceps, and Wrist.1 Using Abdomen Circumference to Predict Body Fat Figure 1 shows the data and regression line for using weighl. to predict body fat percentage. Figure 2 shows the data and regression line for using abdomen circumference to predict body fat percentage. 40 I 10 o I A I so ' an f." a I I I S . . u I. l i m g 20 . ' ' 5".

Johnson in "Fitting Percentage of Body Fat to Simple Body Measurements,\" Journalof Statistics Education. [1996). http://www.amstat.org/pu blicati ons/jse/v4n 1/datasets .johnson.html. (a) Which scatterplot, the one using Weight in Figure 1 or the one using Abdomen in Figure 2, appears to contain data with a larger correlation? 0 Weight 0 Abdomen eTatbook and Media Hint (b) In Figure 2, one person has a very large abdomen circumference of about 127 cm. Estimate the actual body fat percent for this person as well as the predicted body fat percent. Round your answers to the nearest integer. observed body fat = v 96 predicted body fat = v 96 eTextbook and Media Hint (C) Use Figure 2 to estimate the abdomen circumference for the person with about 40 '7: body fat. In addition, estimate the residual for this person. Round your answers to the nearest integer. Abdomen circumference = v cm residual : v 96 eTextbook and Media Hint Save for Later Attempts: 0 of 3 used
