I need help on this question:

Explain the difference between a simple random sample and a systematic sample. (Select all that apply.)

In a simple random sample, the clusters to be included are selected at random and then all members of each selected cluster are included.

In a simple random sample, the only samples possible are those including every kth item from the random starting position.

In a systematic sample, the clusters to be included are selected at random and then all members of each selected cluster are included.

In a systematic sample, the only samples possible are those including every kth item from the random starting position.

In a systematic sample, every sample of size n has an equal chance of being included.

In a simple random sample, every sample of size n has an equal chance of being included.

In a simple random sample, random samples from each strata are included.

In a systematic sample, random samples from each strata are included.
