Fit a KNN model to the Titanic Passengers dataset where "Survived" is the response and all other variables (except Name) are the predictor (X) variables. Set the validation to the validation column. Set the K to 15, and the random seed to 125. Based on the results, what is the optimal K (enter the numerical answer, e.g., 3)

You should probably post this in the JMP Communities.

KNN model is an unsupervised model . and it has nothing to do with Y/response variable ("Survived" ).
about your Q, K is difficult to decide , my opinion is using Principle Component Analysis to plot a X-Y scatter graph by first two principle component . and Check how many clusters should be divided.
@Rick_SAS wrote a blog about it .
