The purpose of this activity is to find a model for linear data and to make predictions.
Everyone will be working with the same two pieces of data but you will be asking different people and therefore will have slightly different results. Your goal is to find the relationship between height (in inches) and shoe size.
1. Ask 10 different people how tall they are (in inches) and their shoe size. Record your responses in a table here. (+5)
2. Put your paired data into statcrunch and run the linear regression. What is the equation of your line of best fit? (+2)
3. Using your equation from statcrunch, predict the shoe size of someone who is 60 inches tall. (+2)
