6. Based on the following confusion matrix with a validation set of 100, class 1 reflects the members targeted who purchased services and class O reflects the non-targeted respondents who did not purchase services. Calculate the sensitivity rate. Actual Class Class 1 Class o Predicted Class 1 18 11 Predicted Class 2 11 60 A. 78% B. 84% C.62% D. 32% | 7. The root mean square error calculation is: 71 B = yei 12 C. =y-9 D 8. The following table displays the weights for computing the principal components and the data for two observations. The mean and standard deviation for x are 4.2 and 1.4, respectively. What is the Z-score of x for observation 1?
