| After launching an advertising campaign encouraging people to read books, a survey was conducted to assess responders reaction to the campaign. Given responders data. we are interested in predicting their new reading habits after the campaign. Is this a regression or a classication problem? O This is both a classifcation and a regression problem. The output variable is both discrete and continuous. O This is a regression problem. The amount of time spent reading book after the campaign is a continuous random variable. O The question does not make sense. We need additional information on the output variable and how it was measured when the survey was conducted before we can say whether it is a classication or a regression problem. O This is a classication problem. The number of books read after the campaign is a discrete random variable
