Question 3 10 points Save Answer 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 classification problem? O This is a regression problem. The amount of time spent reading book after the campaign is a continuous random variable. O This is a classification problem. The number of books read after the campaign is a discrete random variable. O This is both a classifcation and a regression problem. The output variable is both discrete and continuous. O The question does not make sense. We need additional information on the output variable and how it was measured when the survey was conducte before we can say whether it is a classification or a regression problem.
