D [+] Assume we want to do a regression analysis. i. Find the correlation coefficient. Round your answer to four decimal places. r= 0.60: ii. Does it actually make sense to use the line for predictions? Do a hypothesis test with a=0.05 and explain your answer. You may want to reference a e Critical Values Table [+] (there is also one in your textbook). iii. What percent of the variation in weight can be explained by variation in height? About % of the variation in weight can be explained by variation in height. Give your answer as a whole number. iv. Find the equation for the regression line. (Please do this even if it does not make sense to use the line for predictions.) Round your answers to one decimal place. y =
