Here are those 23 ages (in years). 32, 41, 43, 46, 52, 53, 54, 55, 62, 63, 63, 63, 64, 65, 65, 68, 69, 69, 72, 73, 75, 75, 78 Send data to calculator Frequency 10- 8- 6+ 4- 2- 0 30 one. 40 3 4 50 Age (in years) 60 (a) For these data, which measures of central tendency take more than one value? Choose all that apply. (b) Suppose that the measurement 32 (the smallest measurement in the data set) were replaced by 26. Which measures of central tendency would be affected by the change? Choose all that apply. (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 10 70 5 80 Mean Median Mode None of these measures Mean Median Mode None of these measures Mean Median Mode None of these measures ONegatively skewed Positively skewed O Roughly symmetrical
