an internet service provider (ISP) has randomly selected a sample of 223 observations concerning values of the response variable churn and several predictor variables based on customer activity during the most recently billed month. Here churn equals yes if a customer churned- left the internet service provider for another ISP- and equals No otherwise. The predictor variable minuteson is the average daily minutes the customer spent online. Emailsent is the average daily number of emails the customer sent from the average daily number of emails the customer sent from the email address provided by the ISP.
