Question

The standard deviation of 25 numbers is 40,if each of the numbers is increased by 5,then new standard deviation is

Answer 1

Answer:

40

Step-by-step explanation:

Given the standard deviation of 25 numbers is 40,if each of the numbers is increased by 5,then new standard deviation is

Now let us remember one point that if each item of data is either decreased or increased by the same constant then the standard deviation of the data is not changed or remains unchanged.

hence the standard deviation is 40.

Answer 2

Answer of this question is 40.

Because we know that if each term of data is either increased or decreased by the same constant number then the S.D (standard deviation) of the data is remains unchanged. And in question its already given that the standard deviation of 25 numbers is 40.

So, the Standard Deviation is remains 40.
