Step by step solution

01

Given information

The sample data of students and the faculty members is provided.

02

Concept

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.

03

Calculation

A convention can be attended by four students and two faculty members. It decides on a random selection of those who will go.

Based on their position in the alphabetical ranking, the student is assigned a unique number between 1 and 30

Line 123 from table D:54580815072710256027558923306341842815683

Select the relevant student for every 2 consecutive digits if the number is between1 and 30, otherwise move on to the next 2-digit number:

Based on their position in the alphabetical ranking, each faculty member is assigned a unique number between 0 and 9.

Line 123 from table D: 54580815072710256027558923306341842815683

Select the two faculty members who match to the first two digits (after 27):
