The northern lights (or Aurora Borealis) appear on some nights during the winter in Alaska. The nights on which they appear occur at random. The website for a hotel you are planning to visit in Alaska shows that the northern lights have appeared 593 nights over the past 210 winter weeks. Suppose that you randomly pick a week next winter to visit. What are the mean and standard deviation of the number of nights the northern lights appear the week you visit? To answer, use the data shown on the hotel's website and assume that the number of nights the northern lights appear follows a Poisson distribution. Round your answers to two decimal places. (a) mean: (b) standard deviation:|
