Kerin discovered that a human’s height is related to his or her reach. Kerin is curious if the same thing is true for foot size. 1-30 HW eTool (Desmos).

1. It was not practical for Kerin to measure her classmates’ feet, so Kerin collected the following shoe-size data from some of her classmates. Make a graph with appropriately scaled axes.

   Shoe Size	Height (cm)
   6	153
   8	160
   7.5	155
   8.5	161
   8	168
   8	166
   8.5	164
   6.5	156
   10	170
   9.5	167
   7.5	158
   7.5	156
   8	161

   Hint 1 (a):

   What are the largest and smallest values? Consider shoe size and height independently.

   Hint 2 (a):

   Does it matter which data is on the x-axis and which is on the y-axis?

2. Is there a relationship between shoe size and height?

   Hint (b):

   Examine the scatterplot you made in part (a). Estimate a line of best fit to help you see any trends.
