The mean of a certain number of observations is m. If each observation is divided by `x(ne 0)` and increased by y, then

Mean of certain number of observations is barx . If each observation is divided by m( m ne 0 ) and then increased by n, then the mean of new observation is

Mean of a certain number of observations is x . If each observation is divided by m(m!=0) and increased by n , then the mean of new observation is (a) ( x )/m+n (b) ( x )/n+m (c) x +n/m (d) x +m/n

Mean of a certain number of observations is x . If each observation is divided by m(m!=0) and increased by n , then the mean of new observation is (a) ( x )/m+n (b) ( x )/n+m (c) x +n/m (d) x +m/n

Mean of a certain number of observations is bar(x) If each observation is divided by m(m!=0) and increased by n, then the mean of new observation is

The mean of a set observations is bar(x) . If each observation if divided by alpha (!= 0) and it is increased by 10, then the mean of the new set is

The arithmetic mean of a set of observations is bar(X) . If each observation is divided by alpha and then is increased by 10, then the mean of the new series is

The arithmetic mean of a set of observations is bar(X) . If each observation is divided by alpha and then is increased by 10, then the mean of the new series is

The mean of a set of observations is bar(x) . If each observation is divided by alpha, alpha ne 0 and then is increased by 10, then the mean of the new set is :
