Exercise 2.
NFL teams play 16 games during the regular season. Suppose the
standard deviation of the number of games won by all teams is 2,
and the correlation between the number of games a team wins in two
consecutive seasons is 0.5. If a team goes 12 and 4 during a
season, what is your best prediction for how many games they will
win next season?

3. In a National Football League (NFL) regular season, each team plays 16 games. Let " wins" be the number of regular season wins by a team in a particular season (taking a tie as half a win.) Since on average teams win half their games, the distribution of team wins has mean 8. Assume the distribution of team wins stays about the same from year to year. There is a positive correlation between a team's wins one year and...

College football season will be upon us soon. There are 130 big-time (D-1) teams, which play a 12 game (regular season) schedule. Each game starts with a coin toss, which gives a valuable choice to the team winning the toss. Use the Bernoulli distribution to simulate this activity. Simulate coin toss results for each team during the season. Count the cumulative coin toss wins. Graph the results in a histogram and attach it. Describe the histogram (one sentence). How many...
