A) Find the correlation coefficient. Round your answer to two decimal places.
B) This is statistically significant, at 0.05, so we can use it to make predications. Find the regression line if we want to predict weight based on knowing height. Round your answers to 2 decimal places.
C) What percent of variation in weight can be explained by variation in height?
