If each observation is divided by a

then new mean = x¯¯¯a

Now, each item is increased by 10

Required mean = x¯¯¯a +10

=x¯¯¯+10aa

Ans : (C)

Step-by-step explanation:

answer of your question is New mean = (m+xy) /x

Step-by-step explanation:

We are given the following in the question:

Mean of certain number of observations = m

Formula:

If each observation is divided by x and then increased by y, then

Thus, the mean is divided by x and then increased by y.
