Shoe Size
a. From the scatterplot points, estimate a range of heights for students with a size 8 shoe.
b. Use the equation of the regression line to calculate the predicted height of a student with a size 8 shoe. Do not round your answer.
c. The data values are fairly close to the line, so we can say we there is a moderate association. Can we be very confident, moderately confident, or not at all confident that this
prediction is close to the actual mileage? Explain.
