For Analytic Solver, partition the data sets into 50% training, 30% validation, and 20% test and use 12345 as the default random seed. When searching for the optimal value of k, search within possible k values from 1 to 10. If the predictor variable values are in the character format, then treat the predictor variable as a categorical variable. Otherwise, treat the predictor variable as a numerical variable. The accompanying file contains 60 observations with the binary target variable y along with the predictor variables x and x- PictureClick here for the Excel Data File a. Perform KNN analysis. What is the optimal value of K? Enter the optimal k in the box below: Optimal k b-1. Report the accuracy, specificity, sensitivity, and precision rates for the test data set. (Enter your answers as decimals and round them to 2 decimal places.) Accuracy Specificity Sensitivity Precision
