Use the data below (the 2011 season (1) number of offensive fumbles +interceptions (giveaway) and (2) wining percentage of eight randomly selected NFL teams) to answer the following questions.
Giveaways 21, 14, 24, 17, 35, 10, 30, 21
Win% 0.6250, 0.9375, 0.5625, 0.8125, 0.3125, 0.8750, 0.3750, 0.5000
1. Compute the IQR for Win%
2. Compute the covatiance between Giveaways and Wins%
3. Compute the correlation between Giveaways and Win%
