(Espanol An intelligence test that has a maximum time for completion of 45 minutes was recently administered to a group of 21 people. Their respective times for completion (in minutes) were as follows. 21, 28, 31, 32, 33, 34, 36, 36, 37, 37, 39, 39, 39, 41, 41, 41, 41, 41, 41, 41, 43 Send data to calculator Send data to Excel Frequency 8 8 7 6- 4 0 20 25 30 35 40 45 Time for completion (in minutes) OMean (a) For these data, which measures of Median central tendency take more than one value? Choose all that apply. OMode None of these measures (b) Suppose that the measurement 21 (the Mean smallest measurement in the data set) were Median replaced by 9. Which measures of central tendency would be affected by the change? Mode Choose all that apply. None of these measures (c) Suppose that, starting with the original OMean data set, the smallest measurement were Median removed. Which measures of central tendency would be changed from those of OMode the original data set? Choose all that apply. ONone of these measures (d) The relative values of the mean and median for the original data set are typical of OMean is greater data that have a significant skew to the left. What are the relative values of the mean and OMedian is greater median for the original data set? Choose OCannot be determined only one
