Answer:

The requirements that must be satisfied are A and D

Step-by-step explanation:

The sample observations must be a simple random sample. Where the simple random sample should not greater than 30

And

Either the population is normally distributed, or n>30, or both.

The requirement that should be satisfied is

A. The sample observations must be a simple random sample.

D. Either the population is normally distributed, or n>30, or both.

Requirement that needs to be satisfied:

Here the sample observations should be random simple also the simple random sample should not be more than 30. Moreover, the population should be normally distributed

Therefore, we can say that the option A and option D should be correct.

And, the rest of the options are incorrect.
