Shoe Size and Height

Determine the shoe size and height of 8 to 10 adults. Before you begin analyzing the data, begin your project report by predicting whether or not shoe size and height are highly correlated. Explain why you might expect this.

Using a statistical package or a graphing calculator produce a scatterplot for your data set and find the "best fit'' line.

Interpret the R² value for this line.

Does the data support your hypothesis that you made about shoe size and height? Explain.

Use the equation of the least-squares line to predict the height of Shaquille O'Neal given that he wears a size 22 shoe. How close is your prediction to Shaquille's actual height? Explain what factors might have influenced the reliability of your prediction.
