Answer:
10"
Step-by-step explanation:
The volume for a cube is V = l × w × h
But since this is a cube, all the sides aree the same length, so we could rewrite this in terms of x as:
V =
If we know the volume to be 1000, we sub it in for V:
We "undo" a cube by taking the cubed root of both sides. The cubd root of x cubed is just x, and the cubed root of 1000 is 10. Therefore, x = 10
Considering the situation described, the null hypothesis is given as follows:
.
At the null hypothesis, it is tested if the <u>mean is the same as in the Census</u>, of $64,000, hence:
.
At the alternative hypothesis, it is tested if the mean is different from the Census, hence:
.
