We looked at the number of pre-season wins and regular season wins for all 32 NFL teams over a 10 year span. (a) What would a positive association imply about the relationship between pre-season and regular season success in the NFL? O More wins in the pre-season is associated with more wins in the regular season. O More wins in the pre-season is associated with fewer wins in the regular season. O There is almost no association between the number of wins in the pre-season and the number of wins in the regular season. eTextbook and Media (b) What would a negative association imply about the relationship between pre-season and regular season success in the NFL? O More wins in the pre-season is associated with more wins in the regular season. O More wins in the pre-season is associated with fewer wins in the regular season. O There is almost no association between the number of wins in the pre-season and the number of wins in the regular season. eTextbook and Media (c) The correlation between these two variables is r = 0.067. What does this correlation tell you about the strength of a linear relationship between these two variables? O There is a strong positive correlation between the variables. O There is a strong positive relationship but we cannot conclude causation. O There is almost no linear relationship between the two variables. eTextbook and Media
