A) \[\overline{X},M.D.\]
B) \[\overline{X}+5,M.D.\]
C) \[\overline{X},M.D.+5\]
D) \[\overline{X}+M.D.+5\]
Correct Answer: B
Solution :
Let \[{{x}_{i}}\] be n observations, i = 1, 2, ...n Let \[\overline{X}\] be the mean and M.D be the mean deviation about \[\overline{X}\] . If each observation is increased by 5 then new mean will be \[\overline{X}+5\] and new M.D. about new mean will be M.D. be M.D. \[\left( \because Mean=\sum\limits_{i=1}^{n}{\frac{{{x}_{i}}}{n}} \right)\]You need to login to perform this action.
