(c) Suppose that, starting with the original data set, the smallest measurement were removed. Which measures of central tendency would be changed from those of the original data set? Choose all that apply. (d) Which of the following best describes the distribution of the original data? Choose only one. Mean Median Mode None of these measures Negatively skewed Positively skewed Roughly symmetrical A survey of 23 retirees was taken. Among other things, the retirees were asked to report the age at which they retired. Here are those 23 ages (in years). 34, 41, 43, 43, 53, 53, 53, 59, 61, 61, 62, 62, 65, 66, 66, 68, 68, 69, 71, 72, 73, 74, 77 Frequency 10 8- 6- Recta10 ular Snip 5 4 4 3 2. 30 40 50 60 70 80 Age (in years) Mean (a) For these data, which measures of central tendency take more than one value? Choose all that apply. (b) Suppose that the measurement 34 (the smallest measurement in the data set) were replaced by 25. Which measures of central tendency would be affected by the change? Choose all that apply. Median Mode None of these measures Mean Median Mode None of these measures
