Question

The list {17, 13, 5, 10, 14, 9, 12,16}are the points scored in a test. Which two scores can be removed without changing the meanvalue of the list?

Answer 1

Answer:

10 and 14

Step-by-step explanation:

Let find out the mean value of the given numbers

Mean = Sum of the marks / number of marks

Mean = 17+13+5+10+14+9+12+16

8

= 96 = 12

8

As mean is 12 we can remove two numbers whose sum will be 24 ( 12*2 )

In the give number we can select 10 and 14 whose sum will be 24. So that that the mean valie will not be changed

Mean ( new ) = 17+13+5+9+12+16

6

= 72 = 12

6
