Research Question 1: How do Cal Poly students compare to the recommended 10-15% of body weight?

Recall the backpack study from Investigation 1. Recreate the backpack to body weight ratios (e.g, in Column C, use =a2/b2 and then double click on the lower right corner to fill down the column)

(a) Produce a graph to display the distribution of backpack to body weight ratios and summarize what you learn.

 

 

(b) Produce a graph to display the distribution of the variable whether or not the ratio is less than 0.10 and summarize what you learn.

 

 

(c) Which variable do you think it more informative? Explain.
