Directions

Use the drop-down menu to learn about the three steps needed to complete this assignment.

Three steps to complete the assignment

Step 1: Review the Rubric

Before you submit your work, review the rubric at the bottom of this assignment.
Use the rubric as a checklist to determine whether you are ready to submit your work.

Step 2: First Draft

Commit a good-faith effort to address each item in the Prompt section below.
Please be sure to number your responses and include “white space” between problem numbers. This improves the readability and flow of your work. I cannot give feedback and grade jumbled work.
Use either of the following options to submit your work.
OPTION 1: You can submit a text-entry assignment (i.e. typing your answers in Canvas). To learn how to submit a text-entry assignment, use these (opens in a new tab).
OPTION 2: You can upload your paper-and-pencil work (or the digital equivalent). To learn how to upload your paper-and-pencil work, use these (opens in a new tab). WARNING – some file types may not be visible on my end. So to learn which files you can upload, be sure to use the directions link I provided for this option.
Not ready to submit a good-faith effort yet? Avoid frustration – use the link to the Questions, Answers, & Tips discussion board (at the bottom of this page) to post questions about this assignment (or visit the discussion board to answer your classmates’ questions). You can also contact me directly (see the homepage for my contact information).

Step 3: Optional Final Draft

After you submit your good-faith attempt to fully respond to the questions in the Prompt section below, advance to the ANSWER(S) page.
You can use the ANSWER(S) page to correct your work and resubmit this assignment any time before I begin grading the problems. However, to earn full credit, you are not required to submit a final draft for this assignment. But if you do submit a final draft, I will only grade it if you submitted a good-faith effort on your first draft.
Warning – I will only grade your most recent submission. So if you choose to submit a final draft, please do not leave anything out, and please do not direct me to read an earlier submission. To maximize your score, your most recent submission (at the time I begin grading) must be complete.

Context

Students researching backpack weights gathered data from 45 elementary school children in the 3rd and 5th grades. The variable is percent of body weight carried in the school backpack. So a child who weighs 60 pounds and carries 9 pounds has a variable value of 15% (9 60 = 0.15 = 15%). The American Chiropractic Association (ACA) recommends that children carry no more than 10% of their body weight.

Prompt

When we analyze backpack weight as a percentage of body weight, how do 3rd and 5th graders compare? Are children in this study following the ACA recommendation?

$distribution of percent-of-body-weight carried: stacked histograms (3rd graders, 5th graders)$

Percent of Body Weight Carried
% of body weight carried in backpack	Third graders	Fifth graders
0-5%	1	1
5-10%	6	6
10-15%	11	4
15-20%	3	7
20-25%	0	1
25-30%	0	2
30-35%	0	1
Totals	21	22

Note: Left-hand end-points are included in each bin. So the 2nd bin contains students carrying 5% of their body weight.
