The well-known geyser "Old Faithful" has a very predictable schedule for when it erupts. However, for the nearby Beehive Geyser, the eruptions occur at randomtimes. In trying to provide visitors information on their chances of seeing Beehive Geyser erupt, park officials have recorded eruptions over the past 265 days.During this period, there were 162 eruptions.Suppose that we randomly select a day in the future. Using the data from the park officials and assuming that the number of eruptions follows a Poissondistribution, what are the mean and standard deviation of the number of eruptions that occur over the day selected? Round your answers to two decimal places.(a) mean: 0.611?(b) standard deviation:0.782

QUESTION 5 Any basketball fan knows that Shaquille OʻNeal, one of the NBA's most dominant centers of the last twenty years, always had difficulty shooting free throws. Over the course of his career, his overall made free-throw percentage was 53.3%. During one off-season, Shaq had been working with an assistant coach on his free-throw technique. During the next season, a simple random sample showed that Shaq made 26 of 39 free-throw attempts. Test the claim that Shaq has significantly improved his free-throw shooting using a 0.05 significance level. Check the conditions of the Central Limit Theorem for this scenario. Calculate the number of expected successes.

This cumulative review problem uses material from Chapters 3, 5, and 10. Recall that the Poisson distribution deals with rare events. Death from the kick of a horse is a rare event, even in the Prussian army. The following data are a classic example of a Poisson application to rare events. The data represent the number of deaths from the kick of a horse per army corps per year for 10 Prussian army corps over a period of time. Let x represent the number of deaths and f the frequency of x deaths. x 0 1 2 3 or more f 111 61 24 4 (a) First, we fit the data to a Poisson distribution.The Poission distribution states P(x) = e−λλx x! , where λ ≈ x (sample mean of x values). From our study of weighted averages, we get the following. x = Σxf Σf Verify that x = 0.605. Hint: For the category 3 or more, use 3. x = (b) Now we have P(x) = e−0.605(0.605)x x! for x = 0, 1, 2, 3 . Find P(0), P(1), P(2), and P(3 ≤ x). Round to three places…
