The authors of a paper presented a correlation analysis to investigate the relationship between maximal lactate level x and muscular endurance y. the accompanying data was read from a plot in the paper. x 400 750 770 800 850 1025 1210 1240 1310 1410 1475 1480 1505 2200 y 3.80 4.10 4.90 5.20 4.10 3.50 6.20 6.88 7.55 4.95 7.90 4.45 6.60 8.90 sxx = 2,635,430.357, syy = 37.4976, sxy = 7536.075. a scatter plot shows a linear pattern. compute the value of the sample correlation coefficient, r. round your answer to four decimal places. r
