10. You are in charge of assessing different training methods for effectiveness. You have data on 4 methods: Method 1 (X = 87, n = 12), Method 2 (X = 92, n = 14), Method 3 (X = 88, n = 15), and Method 4 (X = 75, n = 11). Test for differences among these means, assuming SSB = 64.81 and SST = 399.45.
