A certain article reported the following observations, listed in increasing order, on drill lifetime (number of holes that a drill machines before it breaks) when holes were drilled in a certain brass alloy. 10 14 20 23 31 37 39 44 47 50 59 61 64 67 77 78 69 70 73 75 93 95 98 101 105 82 85 86 90 91 147 157 106 106 111 119 123 137 140 141 160 169 185 207 247 264 290 323 387 513 USE SALT Compute the sample median, sample mean, 10% trimmed mean, and 25% trimmed mean for the lifetime data. (Round 25% trimmed mean to four decimal places.) sample median 92 sample mean 119.32 10% trimmed mean 25% trimmed mean 102.2750 95.4615 X Compare these measures. All four values have about the same value. The mean is somewhat larger than the median and the 10% trimmed mean is closer to the mean while the 25% trimmed mean is closer to the median.

USE SALT
Compute the sample median, sample mean, 10% trimmed mean, and 25% trimmed mean for the lifetime data. (Round 25%
trimmed mean to four decimal places.)
