Document Summary
Answer key: each of the following statements applies to the data distribution pictured to the right. Determine whether the given statement is sensible and explain why it is or is not. 1a) [6] marfenstra concludes that the high values are outliers, and therefore can de disregarded. Not sensible while the high values may indeed be outliers, they cannot be simply disregarded. While high values may be unlikely, they are possible, and therefore may be valid. 1b) [6] nuenstra concludes that the mean must be larger than the median. Sensible the data is skewed to the right, which will pull the median above the mean. 1c) [6] oleanstra concludes that the mode must be larger than the mean. 2a) [7] let m and x represent the median and mean scores. The scores in order are 75, 75, 75, 80, 85, 90, 90. The median is in the middle: m = 80. respectively. So m x = 80 81. 43 = 1. 43.
