Explanation of Solution

Given info:

The A & M student body has nearly 46,000 members.

Justification:

Here, the objective of the administrator is to estimate the percentage of students who are the first in the family to go to college.

Population of interest:

The population of interest includes all the individuals of interest. The overall group of objects about which the conclusions are to be drawn is called the population.

Here, the population of interest is the students in the A &M University.

Sample:

A subset or portion of the population that is actually obtained and that is used to draw the conclusions about the population is called a sample.

The steps to estimate the percentage of students who are the first one to join in the college from the family are as follows:

  • To reach the objective first, the administrators has to take a survey.
  • A sufficiently large sample has to be drawn from the A & M University.
  • The sample has to be drawn using simple random sampling method, where each students from University should have equal to chance to include in the sample.
