Question

If each observation of a set is divided by 5, then the mean of new
values :
(a) is 5 times the original mean
(b) is decreased by 5
(c) is (1/5)th of the original mean (d) remains the same
​

Answer 1

Answer:

If each observation is divided by 5, then the mean of new set of observation is 1/5th of the original mean.

so option c is correct

Answer 2

Answer:

The answer is option (c)

Given problem:

If each observation of a set is divided by 5, then the mean of new values :

(a) is 5 times the original mean

(b) is decreased by 5

(c) is (1/5)th of the original mean

(d) remains the same

Step-by-step explanation:

Note: in a AP if each observation is divided by a number "n" then the new mean will be (1/n)th of the original mean  

If each observation of the set is divided by 5 then the mean of new values is (1/5)th of the original mean.

the answer is option (c)
