A sample of n=8 scores has a mean of m=12. What is the value of ∑x for this sample
Answer: We are given the mean of 8 scores is 12.
We are required to find the sum of these 8 observation's, 
We know that:
We are given:
Hence, sum of 8 observation's, 
Answer:
x=0.3

The width is basically the diameter:
Given
Diameter = 5.5 cm
So Radius =
=
= 2.75 cm
Height of cylinder = 12.5 cm
Formula of the volume of a cylinder
V = Area of base × height of prism
=
r² × h
=(2.75)² (
) × 12.5
=7.5625
× 12.5
≈ 296.83 cm³
