Suppose that we would like to select between two prediction models, M₁ and M₂. We have performed 10 rounds of 10-fold cross validation on each model, where the same data partitioning in round i is used for both M₁ and M₂. The error rates obtained for M₁ are 30.5, 32.2, 20.7, 20.6, 31.0, 41.0, 27.7, 26.0, 21.5, 26.0. The error rates for M₂ are 22.4, 14.5, 22.4, 19.6, 20.7, 20.4, 22.1, 19.4, 16.2, 35.0. Comment on whether one model is significantly better than the other considering a significance level of 1%.
