Exercise Set E: 1, 2, 3

Also:
   - Suppose the following 20 birth weights (in ounces) were recorded at a maternity ward: 131, 120, 112, 88, 114, 128, 133, 104, 108, 94, 133, 124, 84, 132, 107, 144, 93, 114, 116, 120. Use R to compute the the first and third sample quartiles of the birthweights, and the interquartile range.
   - For the data in [[http://dananne.org/fu/courses/math-241/R/height.txt|http://dananne.org/fu/courses/math-241/R/height.txt]], use R to compute (a) the first and third sample quartiles, (b) the 60th sample  percentile, and (%%c%%) the 10th sample percentile.

Answers:
  - First quartile: 106.2; Third quartile: 128.8; Interquartile range: 22.6
  - (a) First quartile: 66.39; Third quartile: 72.03 (b) 70.38 (%%c%%) 63.69
