company wishes to purchase one of five different printers: A, B, C, D and E. In an experiment designed to test whether there is a difference in the printer's performance, each of five experienced operators works on each of the machines for equal times. The table shows the no of printed materials produced per printer. Test the hypothesis that there is no difference between the printers at significant level of (a) o.05 and (b) o.01 A 68 72 77 42 53 B 72 53 63 53 48 60 82 64 75 72 48 61 57 64 50 E 64 65 70 68 53
