11. Three training methods are employed and then compared to determine if there are differences in the productivity levels of the three groups that are trained. A sample of five trainees each is taken from the three groups. The productivity levels are as follows: Method 1: 85 60 75 80 65 Method 2: 70 82 62 65 68 Method 3: 85 82 78 80 79 At 1% level of significance, do the training methods yield significantly different productivity levels? (and therefore, significantly different training methods)?
