Cellphоne Custоmer Retentiоn: k-Neаrest Neighbors. Apply k-neаrest neighbors to clаssify observations as churning or not by using Churn as the target (or response) variable. cellphonechurn.csv #Use first 1500 of the data for training and use remaining observations as a test set.  #The branch will only extend up to level 5, and if a node has less than 2 observations, the node will not be split any further. #Additionally, each node must have at least 1 observations. If the threshold is 0.5 (i.e., >0.5), how many observations among the observations 1650 to 1659 are classified as “Yes”? [value1] Calculate the accuracy when the threshold is 0.5 (i.e., >0.5) (round to 3 decimal places. You may use round(num, 3) function) [value2] Calculate the accuracy when the threshold is 0.7 (i.e., >0.7)  (round to 3 decimal places. You may use round(num, 3) function) [value3]
