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: 400 740 770 810 850 1035 1190 1240 1290 1390 1475 1480 1505 2200
y: 3.80 4.10 4.80 5.30 3.90 3.40 6.20 6.88 7.55 4.95 7.90 4.45 6.70 8.90

Sxx = 2,648,130.357, Syy = 36.7376, Sxy = 7408.225.

a. Compute the value of the sample correlation coefficient, r. Round your answer to four decimal places.
b. Calculate the test statistic and determine the P-value. (Round your test statistic to two decimal places and your P-value to three decimal places.)
