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. 410 740 760 790 840 1,015 1,190 1,260| 1,290| 1,390 1,465 1,470 1,515 2,190 3.90 4.10 4.80 5.30 3.90 3.40 6.20 6.98 7.65 4.85 7.90 4.55 6.50 8.80 S- 2,615,458.929, S- 38.0587, S 7,437.889. A scatter plot shows a linear pattern. (a) Test to see whether there is a positive correlation between maximal lactate level and muscular endurance in the population from which this data was selected. (Use a = 0.05.) State the appropriate null and alternative hypotheses. O Ho: p = 0 H,ip > 0 O Hoi p = 0 O Ho: p #0 O H: p= 0 Compute the value of the sample correlation coefficient, r. (Round your answer to four decimal places.) %3D
