For questions 3 and 4, select a variable from calories, sodium, potassium, or rating to use in both questions.

Making comparisons a) Create and interpret a side-by-side box-and-whiskers plot for the variables carbo and sugars. Identify the five-number summary for each variable.  Embed the image, completed with labels, into the answer field. b) What do the boxplots suggest about the shapes of the frequency distribution for the variables carbo and sugars? c) Based on the boxplots and number summaries alone, answer the following: Do you think the mean is greater than, equal to, or less than the median of these variables? Support your answer with references to the boxplot. Which of these two variables do you think has the greater standard deviation? Support your answer with references to the boxplot.

Visual Display a) Prepare an appropriate graphical display of the number of cereals in the study by manufacturer. Download the image from StatCrunch or other tool and embed it into the answer field. b) Identify the type of display selected and explain why your choice is both appropriate and the best option for presenting the information.
