To choose random samples, we must explain why we should not always start at the same point in Table D.

A simple random sample (SRS) of size n is made up of $n$ people chosen from the population with an equal chance of being the sample that is actually chosen.

Each row of $40$numbers has exactly four $0s$Each row of $40$numbers has exactly four $0s$This assertion is false because if it were true, we would know if the $40$number was a$0$ after looking at $39$digits, and it would become a predictable rather than random digit.

Each digit pair has a $1/10$ chance of being $00$

Each digit pair has a $1/10$ chance of being $00$ Because there are $100$ pairings of digits from $00$ to $99$ all of them are equally likely, this assertion is "True." As a result, each pair of digits has a $1/100$ chance of appearing.

Because this pattern is not random, the numbers $0000$ will never appear as a group. This statement is false because $0000$ can appear as a group just as easily as any other string of four numbers.
