Activity 2: Practice calculating and interpreting the mean and standard deviation of a discrete random variable . 1. Organizers of a concert are limiting tickets sales to a maximum of 444 tickets per customer. Let T be the number of tickets purchased by a random customer. Here is the probability distribution of T: 2. Choose the best interpretation of the mean {or expected value} that you found in the previous question a. Most customers will purchase 3 tickets. b. A group of 1D customers will purchase exactly 29 tickets. c. If we look at a large number of customers _.then each customer .on average ,will have purchased about 2.9 tickets . 3. Calculate the variance and the standard deviation of T. Ftound your answer to three decimal places
