1. Solutions

2. 1.33 A. Graph B. Women (5-number summary) 101, 126, 138.5, 154, 200. Men: 70, 98, 114.5, 143, 187. C. Women generally score higher than men. All five stats are higher for women. The men’s scores are more spread out. The shapes of the distributions are roughly similar, each displaying a slight skewness to the right.

3. 1.34 A. Equal, since the distribution is roughly symmetric. B. 42, 51, 54, 59, 69. The median is very close to the mean. C. IQR = 59-51=8 D. Graph E. There are no outliers.

4. 1.35 The IQR is resistant. Answers will vary.

5. 1.36 A. $1735.00 B. Graph. According to the 1.5 x IQR, the outliers are 85.76, 86.37, and 93.34.

6. 1.37 A. Q1 = 25 and Q3 = 45. B. It is not an outlier (75 is the boundary for outliers).

7. 1.38 A. The 5-number summary is 5.7%, 11.675%, 12.75%, 13.5%, and 17.6% B. It would flag Alaska, Florida, and the one with 8.5%
