1. Dogs: Let a be the number of dogs per household in a small town. The probability distribution of r is as follows: (1.5 points each) X 0 1 2 3 4 5 P(x 0.686 0.195 0.077 0.022 0.013 0.007 Find (a) Find P(Less than 3 dogs) (b) Find the probability that a household had at least two dogs. (c) Would it be unusual for a household to have more than two dogs? Why/ why not? Motivate your answer. (d) Compute the mean ur number of dogs per household. (Use your calculator, and write down how you did it!) (z = (e) Compute the standard deviation or of the number of dogs per household. (Use your calculator, and write down how you did it!) oz =
