Create a scatter plot for height and length of foot. We will assume here that height influences length of foot so height will be the independent variable. Does it appear from the plot that there is a relationship between the two variables? What type of relationship would that be?
2. Calculate the correlation coefficient for the two variables. How would you interpret this measure?
3. What would be the hypotheses to test this relationship? Is the relationship significant?
4. Find the regression equation to predict length of foot using height. Write it in slope-intercept format.
5. Use the regression equation to predict a foot length for a height of 62 inches.
