Requirements
It is best if you first prepare your responses outside of Canvas and then transfer the completed work into the provided answer fields. It is not possible to save your work in Canvas without submitting it. However,you may resubmit the assignment any time prior to the deadline.Please note, that a resubmission requires resubmitting responses to ALL questions so that the assignment is presented as a complete response.
Prepare responses to the following using the tool of your choice (StatCrunch, Excel, etc) to create graphsand execute operations, as needed. Download and save the work product (graphs, computations,charts) to be embedded within your response in the provided answer fields.All answers must be visible in the field without the needed to click a link.Access this link for instructions on how toembed an image into the answer field.(Links to an external site.)
Prepare explanations in Word to copy and paste into the answer field when you are ready. Be sure that your explanations demonstrate correct grammar and mathematical notation; the Wyris Equation Editor may be needed to insert special characters.
When you are ready to submit your assignment, click Take the Quiz below, enter the responses in the appropriate fields, and then click Submit Quiz.
Please review the scoring rubric as you complete the assignment in order to earn maximum points.M4 Case Study Rubric.pdf

Use StatCrunch or the tool of your choice to execute the following tasks and then embed (not link) the result into the questions below. Your explanations must demonstrate correct grammatical and mathematical notation.
Flag question: Question 1
Question 1
15pts
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.
Question 2
10pts
Review the variables and scan the responses. For each of the measures of center (mean, median,mode), identify a variable that would be best represented by the measure. Determine the measure and explain why it is the best summary option for the selected variable.
For questions 3 and 4, select a variable from calories, sodium, potassium, or rating to use in both questions.
Question 3
35pts
Organization and Presentation
a) Create a frequency distribution for the selected variable.Present the frequency distribution, with all appropriate labels, in the provided answer field as an embedded image.
b) Create the histogram that displays the frequency distribution in part a). Present the histogram, with all appropriate labels, in the answer field as an embedded image.
c) Create a boxplot for the selected variable and identify the five-number summary. Present the boxplot and five number summary, with all appropriate labels, in the answer field as an embedded image.
d) Based on the results of parts a) - c), do you think the mean is the best measure of central tendency for the selected variable? Explain why or why not?
Question 4
20pts
Numeric Summaries
Use the formulas for grouped data and the frequency distribution created in question 3 to estimate the mean and the standard deviation of the selected variable.Embed images of the work process that support your computations.
Question 5
20pts
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.
