It is computed by determining the mean of a data set after deleting the smallest and largest observed values. Compute the trimmed mean for the data given in the accompanying table. Is the tr immed mean resistant to changes in the extreme values in the given data? Click the icon to view the data table The trimmed mean is (Round to the nearest thousandth as needed.) Enter your answer in the answer box and then click Check AnswerExplanation / Answer
solution : Given data 0.87,0.91,0.89,0.83,0.91,0.88,0.90,0.88,0.88,0.94,0.91,0.97,0.91,0.88,0.88,0.92,0.82,0.86,0.86,0.87,0.86,0.89,0.84,0.85,0.90,0.86,0.87,0.93,0.89,0.79,0.93,0.84,0.90,0.86,0.93,0.91,0.87,0.82,0.81,0.84,0.84,0.88,0.88,0.85,0.81,0.83,0.90,0.86,0.84,0.87
=> ordering of the data as 0.79,0.81,0.81,0.82,0.82,0.83,0.83,0.84,0.84,0.84,0.84,0.84,0.85,0.85,0.86,0.86,0.86,0.86,0.86,0.86,0.87,0.87,0.87,0.87,0.87,0.88,0.88,0.88,0.88,0.88,0.88,0.88,0.89,0.89,0.89,0.9,0.9,0.9,0.9,0.91,0.91,0.91,0.91,0.91,0.92,0.93,0.93,0.93,0.94,0.97
=> deleting smallest and largest observed values
0.81,0.81,0.82,0.82,0.83,0.83,0.84,0.84,0.84,0.84,0.84,0.85,0.85,0.86,0.86,0.86,0.86,0.86,0.86,0.87,0.87,0.87,0.87,0.87,0.88,0.88,0.88,0.88,0.88,0.88,0.88,0.89,0.89,0.89,0.9,0.9,0.9,0.9,0.91,0.91,0.91,0.91,0.91,0.92,0.93,0.93,0.93,0.94
=> trimmed mean ? = ? Xi / n
= sum of trimmed set/total number of trimmed set
= (0.81 + 0.81 + 0.82 + 0.82 + 0.83 +.....+ 0.94)/48
= 41.96/48
= 0.874
