1 Bootprint Mystery

2 Data Indiana State University 408 Students 187 Female 221 Male

3 Strategies & Data Found average ratio of height to shoe size for college men & women Checked reasonableness of ratio & adjusted Range of interest Getguidance.com: 1% of women over 18 have a size 13 foot. 14% of males have size 11 foot. Percentages would be even less in teens Correlates to experience with shoe store inventory

4 Height Expectations Male Mean: 69.5” Median: 70” Mode: 70”
Female (2 at size 12) 70” and 71” tall 73” based on “Regression of the Big-Footed Ladies”

5 Height Expectations

6 Helping the Fuzz Three suspects Any witnesses to match height?
Presumably fit the boot print How tall are they? Any witnesses to match height? How does knowing the predicted height matter when there are three suspects whose heights can be measured?
