 Statistics Wording Problem 1. The mean of 10 observations is 12.5 . While calculating the mean one observation was by mistake taken as -8 instead of +8 . F ... 2. The mean of 10 observations is 35 . While calculating the mean two observations were by mistake taken as 35 instead of 25 and ... 3. The mean of 15 observations is 16.4 . If we remove one observation from it then the mean of remaining observations is 17 , th ... 4. The sum of 15 observation is 343 . If we remove two observation 18 and 26 , then find out the mean of remaining observations. 5. The mean of 5 observations is 20 . If we add one new observation then the new mean of the observations is 25 . So find out ne ... 6. The mean of observation is 10 . If we add 2 and then multiply or divide by 3 in each observation, then find the new mean ? Problem 6 of 6 6. The mean of observation is . If we add and then multiply or divide by in each observation, then find the new mean ?
