Question 1 Researchers recorded the percent body fat and the amount of salt consumed by 15 children The scatterplot below shows how the children's percent body fat is related to the amount of salt they consume odpowy salt -6 % body fat = 42 (a) (1 point) Is the child whose salt consumption is 0.6 and whose percent body fat is 42 likely to be a high influence point for regression? Why or why not? (b) (1 point) The researcher reports that the co-efficient of determination is 26.3%. This tells us that estimates made using the regression line will likely be indicate correct) very accurate / not very accurate because (please explain) ... (c) (1 point) Minitab fits the regression line as Pct body fat = 22.69 +9.874 Salt Please interpret the slope. Nothing selected. Select an object or text to format. (d) (1 point) A researcher says that the relationship shows clearly that increased salt is causing the percent body fat to increase. Please comment briefly on this allegation. Question 2 The data set attached shows the prices of beer and hotdogs at 24 major league baseball parks in the US in 2015. (a) (1 point) Give a point estimate of the average price of a hot dog at all major league baseball parks in the US in 2015 (b) (1 point) Interpret the estimate in (a). 125% lo Collaborate View Zoom Add Page Format Document Insert Table Chart Text Shape Media Comment and men anach u to an emau to me, to be received by 10:30am.
