Homework Answers
df(Regression) = Number of independent variable = 1
df(Total) = n - 1 = 35 - 1 = 34
df(Error) = 34 - 1 = 33
MS(Regression) = 49/1 = 49
SS(Residual) = 34*6 = 204
SS(Total) = 49 + 204 = 253
Fobt = 49/6 = 8.17
Hence,
The complete table will be:

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...
