Answer:
d. 
Step-by-step explanation:
We have been given that Cheng measures each edge of each base to be 2 feet. The height of the whole sculpture is 6 feet.
First of all, we will find height of each pyramid by dividing height of whole sculpture by 4 as:

We know that volume of a pyramid is equal to 1/3 of base area times height that is
, where b represents area of base.

Since volume of one pyramid is equal to 2 cubic feet, so volume of 4 pyramids will be 4 times 2 cubic feet that is 8 cubic feet.
Therefore, Cheng must purchase 8 cubic feet of material.
Answer:
The entire population is measured in both cases, so the actual difference in means can be computed and a confidence interval should not be used.
Step-by-step explanation:
A student working on a report about mathematicians decides to find the 98% confidence interval for the difference in mean age at the time of math discovery for Greek mathematicians versus Egyptian mathematicians. The student finds the ages at the time of math discovery for members of both groups, which include all Greek and Egyptian mathematicians, and uses a calculator to determine the 98% confidence interval based on the t distribution, <u>the entire population is measured in both cases, so the actual difference in means can be computed and a confidence interval should not be used.</u> There is no as such explanation of this scenario, its just the answer mentioned above.
