MEANS.

The two greatest deviations from 

 the mean, viz., 8'' 26"" and 12'' 45"', 

 nearly balance in the mean, hence 

 no value was rejected.

The criterion rejects no value of 

 the interval ; the low value 8'' 29'" 

 is so near the limit of rejection and 

 not balanced in the mean that I 

 prefer to reject It.
