Because the mean is very sensitive to extreme values it is not a resistant measure of center By deleting some low values and high values the trimmed mean is more resistant To find the 10 trimmed mean for a data set first arrange the data in order then delete the bottom 10 of the values and delete the top 10 of the values then calculate the mean of the remaining values Use the axial loads pounds of aluminum cans listed below for cans that are 0 0111 in thick Identify any outliers then compare the median mean 10 trimmed mean and 20 trimmed mean 246 261 268 274 277 280 281 282 284 284 287 288 289 292 294 295 296 300 312 507 Compare the values Choose the correct answer below OA The median untrimmed mean and 20 trimmed mean are close to each other However the 10 trimmed mean is significantly different from those values OB The median 10 trimmed mean and 20 trimmed mean are close to each other However the untrimmed mean is significantly different from those values OC The median untrimmed mean and 10 trimmed mean are close to each other However the 20 trimmed mean is significantly different from those values OD All of the values are close to each other OE The untrimmed mean 10 trimmed mean and 20 trimmed mean are close to each other However the median is significantly different from those values
