Read the statements carefully and state 'T for true and 'F for false.
(i) If the number of observations is odd, then the median is `(n/2+1)^(th)` observation.
(ii) The mean of 25 observations is 18. Out of these observations, the mean of first 13 observations is 16 and that of the last 13 observations is 20. Then, the `13^(th)` observation is 18.
(iii) Mode of the data 17, 21, 11, 48, 35, 11, 19, 17, 12, 13, 11, 15 is 11.
(iv) The mean of first 15 prime natural numbers is 27.5.
