2. The following data refer to Stanford heart transplants. It relates the survival time of patients that have received heart transplants to their age when the transplant occurred and to a so-called mismatch score that is supposed to be an indicator of how well the transplanted heart should fit the recipient. Survival Time (in days) 624 46 64 1,350 280 10 1,024 39 730 136 836 60 Mismatch Score 1.32 .61 1.89 .87 1.12 2.76 1.13 1.38 .96 1.62 1.58 .69 Age 51.0 42.5 54.6 54.1 49.5 55.3 43.4 42.8 58.4 52.0 45.0 64.5
