#### Answer

Set E has a higher average and a larger spread

#### Work Step by Step

Dataset E: 113,183,479,120,117 Dataset F:145,129,153,135,142 Mean E: Add all the numbers and divide by 5 :$\frac{113+183+479+120+117}{5}$=202.4 Mean F: Add all the numbers and divide by 5: $\frac{145+129+153+135+142}{5}$=140.8 Dataset E has the larger average. Range E: The difference between the largest and smallest number:479-113=366 Range F: The difference between the largest and smallest number:153-129=24 Dataset E has the larger spread. Set E has a higher average and a larger spread since its mean and range is larger than F's.
