Before we use an applet to simulate the selection of random samples from this population, let’s make sure we are clear about who
Sauron [17]

Answer:

D) college students

The college students are best describes the population

Step-by-step explanation:

<u>Explanation</u>:-

<u>Introduction</u>:-

The outcome of a statistical experiment may be recorded either as a numerical value or as a descriptive representation.

<u>Example</u>:-

  • when a pair of dice are tossed and the sum of the numbers on the faces is the outcome of interest, we record a numerical value.
  • If the students of a certain school are given blood tests and the type of blood is of interest, we record a numerical value.

In particular study, the number of possible observations may be <u>small, large but finite or infinite.</u>

<u> Example :- 1</u>

In the classification of blood types we can only have as many observations as there are students in the school.

Therefore the results are <u>finite number</u> of observations.

<u>Example :- 2</u>

If we could toss a pair of dice indefinitely and record the sums occur, we would obtain an infinite set of values .

<u>Population</u>:-

The total of observations which we are concerned , whether this number is finite or infinite , this is called the<u> population</u>

The number of observations in the population is defined to be the size of the population.

<u>Example</u> :- If there are 600 students in the school that we classified according to blood group, we say that the population of size is 600.

<u>Sample</u>:- A sample is subset of a population

Therefore in given data

The college students are best describes the population

Female college students , part -time college students , and female part-time college students are samples it will come from population
