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

Which are the solutions of the quadratic equation? x2 = 9x + 6
Lelechka [254]
X^2 = 9x + 6
x^2 - 9x - 6 = 0
use quadratic formula : (-b (+-) sqrt b^2 - 4ac) / (2a)
a = 1, b = -9, c = -6
now we sub

x = (-(-9) (+-) sqrt -9^2 - 4(1)(-6)) / 2(1)
x = 9 (+-) sqrt 81 + 24)/2
x = 9 (+-) sqrt 105) / 2
x = 9/2 + 1/2 sqrt 105 or x = 9/2 - 1/2 sqrt 105
