Consider observations of the number of wins per season by National Football League teams over the years 1989-2008. The observed mean is 8 wins/season and the observed standard deviation is 3.02. A histogram illustrates these data. Referring to these NFL data and assuming normality, the probability that a randomly chosen team wins 10 or more games is? Group of answer choices a. 0.25 b. 0.16 c. 0.09 d. None of these options e. 0.37
The following table shows the number of wins eight teams had during a football season. Also shown are the average points each team scored per game during the 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...
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?
