What is the kappa statistic of the following model? Actual Predicted   no yes no 42 11 yes 3 56   Group of answer choices 0.7987 0.9259 0.9091 0.7473

If two variables X and Y are independent, learning the values of Y does not change the prediction of X. True False

20 observations in the table below are used to train a Naïve Bayes model, and then a prediction is made to a new observation X(C, S) having X1=C and X2=S.
