In a set of 2n distinct observation, each of the observation below the median of all the observations is increased by 5 and each of the remaining observations is decreased by 3. Then the mean of the new set of observations:

In a set of 2n distinct observations, each of the observations below the median of all the observations is increased by 5 and each of the remaining observation is decreased by 3 . Then the mean of the new set of observations

In a set of 2n distinct observations, each of the observations below the median of all the observations is increased by 5 and each of the remaining observation is decreased by 3 . Then the mean of the new set of observations

The median of a set of a observations is 20.5. If each of the largest 4 observations of the set is increasted by 2, then the median of the new set is

The median of a set of 9 distinct observations is 20.5 If each of the largest 4 observations of the set is increased by 2, then the median of the new set :

The mean of a set of observations is a . If each observation is multiplied by b and each product is decreased by c , then the mean of new set of observations is
