If the mean of 8 observations is 25, its total is 25 * 8 = 200.
If the observation 11 is excluded, then the total of 7 observations will be 200 - 11 = 189.
Therefore, the mean of 7 observations with a total of 181 is 189/7 = 27.
If the observation 11 is excluded, then the total of 7 observations will be 200 - 11 = 189.
Therefore, the mean of 7 observations with a total of 181 is 189/7 = 27.
