Complete parts (a) through (c). (a) Find the 10% trimmed mean for the data. The 10% trimmed mean is 0 (Round to the nearest tenth as needed.) (b) Compare the four measures of central tendency, including the midrange. Mean = (Round to the nearest tenth as needed.) Median = Mode= Use a comma to separate answers as needed.) The midrange is found by the following formula. (Maximum data entry) + (Minimum data entry) 2 Midrange = (Round to the nearest tenth as needed.)
