At the Wimbledon Tennis Championship, to win a match in men’s singles a player must win the best of five sets. The following data represent the number of sets played, X, in the men’s singles final match for the years 1968 to 2015.
(a) Construct a probability model for the random variable, X, the number of sets played in the Wimbledon men’s singles final match.
(b) Draw a graph of the discrete probability distribution.
(c) Compute and interpret the mean of the random variable X.
(d) Compute the standard deviation of the random variable X.

The following data represent the number of sets played, X, in the men’s singles final match for the years 1968 to 2015. (a) Construct a probability model for the random variable, X, the number of sets played in the Wimbledon men’s singles final match. (b) Draw a graph of the discrete probability distribution. (c) Compute and interpret the mean of the random variable X. (d) Compute the standard deviation of the random variable X. The data in Table 4 represent the monthly rate of return between 1990 and 2014 for 10 randomly selected months for Cisco Systems stock and 14 randomly selected months for General Electric stock. Does the evidence suggest that Cisco Systems stock is more volatile than General Electric stock at the a = 0.05 level of significance Approach We want to know if the evidence suggests that Cisco Systems is more volatile than General Electric.
