    Researchers were gathering data on alligators in an attempt to estimate an alligator's weight from its length.  They captured 29 alligators and measured their length and weight.  They created three regression models.  Each model, along with its residual plot, is shown below.  y represents the weight in pounds and x represents the length in inches.  Which statement below is true?
    • A.

    • B. 

      There is a linear relationship between weight and length, and Model II is most appropriate.

    • C. 

      There is a non-linear relationship between weight and length, and Model I is most appropriate.

    • D. 

      There is a non-linear relationship between weight and length, and Model II is most appropriate.

    • E. 

      There is a non-linear relationship between weight and length, and Model III is most appropriate.

    Breakfast cereals have a wide range of sugar content.  Some cereals contain High Fructose Corn Syrup (HFCS) as a source of sugar and some do not.  The boxplots below show the total sugar content of different types of cereal for those containing HFCS and for those that do not.  Which statement is true based on the boxplots?
    • A. 

      The number of cereals with HFCS is about the same as the number of cereals without HFCS.

    • B. 

      The cereals with HFCS have a greater interquartile range than the cereals without HFCS.

    • C. 

      The cereals without HFCS have a greater range than the cereals with HFCS.

    • D. 

      About half the cereals without HFCS have less sugar than about three-fourths of the cereals with HFCS.
