The sample of $40$students is given

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

Each student should be alphabetized from $01$ to $40$ Pick a starting point from the random number table. Make a list of two-digit numbers, skipping those that aren't between $01$ and $40$ or are repeats, until you have five distinct numbers between $01$ and $40$

The random digit table will be used to select an SRS in a two-step process.

1) Alphabetically label each student from $1$to $40$Labels $01$to $40$have been added to the alphabetized list of students in the table below:

2) Using the database of random digits Start reading two-digit groupings from the left side of line $107$Because our pupils are designated $01-40$select the first $5$unique numbers ranging from $01-40$which will be selected kids. Because the same student cannot be selected more than once, if the number is repeated, use it just once.

Here is the beginning of the line $107:$

Group the above digits to two digit numbers. We get:$82739578902080747511816765530094383148936094072024$

Our SRS of $5$pilot students was chosen from the class:$$\begin{gathered} 82,73,95,78,90,20,80,74,75,11,81,67, \\ 65,53,00,94,38,31,48,93,60,94,07,20,24 \end{gathered}$$
