2. [110.49 Points] DEVORESTAT9 12.5.061.MI. ASK YOUR TEACHER 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 papen 3.90| 3.40 | 6.40 4.85 | 7.90 | 4.55 SXX = 2,617,358.929, SW = 38.0916, Sxy = 7,446.375. 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 H0: 9 = 0 Ha: p > 0 O Ho: p = 0 Ha: p 0 O HO: p = 0 Ha: I)
