(a)
To explain how would you use a random numbers generator to choose the SRS.
(a)

Explanation of Solution
To choose an SRS,
Let us number the first record as
Once it is labelled in this way, we will follow a simple structure to perform an SRS.
We will draw from the table provided one random number after another.
If the random number drawn is
Also if the same random number comes twice then also we skip the second draw and draw another random number unless we get a different random number from the ones already observed, so that no two records come in the sample.
We continue this procedure until we get
For this problem we are to start at row
The first few random numbers from row
So for random no.
We skip the random numbers
Again for
We need one more. The next few random numbers are
We skip
So the random sample of five is complete. We should continue this method till we have got
(b)
To use your method from part (a) to choose the first three gravestones.
(b)

Explanation of Solution
From the above part (a) the SRS of
Thus, from the above
For example we consider that,
