Question

17. What should be the value of x so that mean of the data is 16
7, 13, 15, 15, 16, x, 19, 20​

Answer 1

Answer:

23

Step-by-step explanation:

mean=16

we know that,

mean=sum of observations/number of observations

16=7+13+15+15+16+X+19+20/8

16=105+x/8

128=105+X

x=128-105=23

Answer 2

Step-by-step explanation:

23

mean of the data is 16

given data:

7, 13, 15, 15, 16, x, 19, 20

mean sum of all observations / number of observations

16=( 7+13+15+15+16+ x+ 19+20)/8

16×8 = 105+x

128-105= x

x = 23
