Triples and Home Runs The data below show the number of three-base hits (triples) and the number of home runs hit during the season by a random sample of MLB teams. Triples     33, 37, 27, 29, 18, 21                   Home runs   305, 345, 245, 265, 155, 185                    The correlation coefficient for the data is r= 1  and a=.01. Should regression analysis be done?                 The regression analysis should not be done or The regression analysis should be done. Find the equation of the regression line. Round the coefficients to at least three decimal places, if necessary y'= a+bx a= b= find y' when x= 28. Round the answer to at least three decimal places, if necessary y'=

Find the equation of the regression line for the given data. Then construct a scatter plot of the data and draw the regression line.​ (Each pair of variables has a significant​ correlation.) Then use the regression equation to predict the value of y for each of the given​ x-values, if meaningful.
