Step-by-step explanation:
The first step is to find the mean of the data set
mean = =
= 5
Next take the absolute value of the difference between each data member and the mean, that is
| 4 - 8 | = | - 4 | = 4
| 3 - 8 | = | - 5 | = 5
| 4 - 8 | = | - 4 | = 4
| 5 - 8 | = | - 3 | = 3
| 6 - 8 | = | - 2 | = 2
| 6 - 8 | = | - 2 | = 2
| 8 - 8 | = | 0 | = 0
| 4 - 8 | = | - 4 | = 4
Finally find the mean of the absolute values
mean absolute value = =
= 3

Answer:
Step-by-step explanation:
The average value theorem sets:
if f (x) is continuous in [a, b] and derivable in (a, b) there is a c Є (a, b) such that
, where
f(a)=f(π/2)=-4*sin(π/2) = -4*1= -4
f(b)=(3π/2)=-4*sin(3π/2) = -4*-1 = 4
⇒
c≅130
