a) What is the population of interest? Approximately, how many people are in the population of interest? (Recall, the definition of a population is: The collection of all outcomes, responses, measurements, or counts that are of interest.)

b) What is the best data collection method to use for the study (explain)? (Recall, data collection methods are: Observation, Survey, Experiment, Simulation).

c) For one of the three studies, a census is possible. Determine which one and then explain why a census is possible for that study and is not possible for the other two studies. (A census means that we are able to collect data from every unit in the population. Most of the time the population is too large for a census to be feasible)

d) For the two studies where a census is not possible, how many people, students, or cars would you sample out of the population? What sampling technique would you use (see section 1.3)? (Explain your reasoning)

Answers

Answer 1

The What is the population of interest are:

GMC students People who own Cars in Macon, GA.People who eat oatmeal in Georgia.

The data collection method according to the group below

SurveySurveyExperiment

What is the statistical studies about?

The best data collection method for the first one oatmeal  and GMC students is survey because the population is large and opinions may differ.

The best data collection method for the cars  is Experiment as one needs to study the cars that pass the red lights

For one of the three studies, a census is possible in the first one because the study population is the Georgia which is very large.

For the two studies the one that a census is not needed is GMC students and cars at red light because the population is not too big.

Based on the study I will use 500 people, 200 students, or 300 cars and the  sampling technique would be Systematic sampling, Simple random sampling and Judgmental/purposive sampling.

A  Simple random sampling is known to be the easiest method of selecting a sample as every member is known to have an equal chance of being selected in the sample.

John has four times as much money as his sister Debbie who has half as much as their friend David. Together the three children have $105. a) How much money does Debbie have? Answer b) How much money does John have? Answer.. c) How much money does David have? Answer.. (1)​

Answers

Let's say that the money that each person has is equal to a letter:

A=Debbie, B=John, C=David.

Now we can write some equations.

"John has four times as much money as his sister Debbie who has half as much as their friend David."

B = 4A

A = 0.5C

"Together the three children have $105"

A+B+C=105

This is now a system of equations problem. Substitute to solve.

A + (4A) + C = 105

(0.5C) + 4(0.5C) + C = 105

3.5C = 105, so C = 30.

Plug this into the previous equations to get A=15 and B=60

So Debbie has $15, John has $60, and David has $30

Here we have the quadratic equation:

There are some ways of solving this, the first approach is completing squares, where we can write:

[tex]2(x^2 + 6x) - 3 = 0\\\\2(x^2 + 2*3*x + 9 - 9) -3 = 0\\[/tex]

Here we add and subtract 9 to complete squares and not change the equation. Here we used the third step only.

Now we just complete squares to get:

[tex]2*(x^2 + 6x + 9) - 2*9 - 3 = 0\\\\2(x^2 + 6x + 9) = 3 + 18 = 21\\\\2*(x + 3)^2 = 21\\\\x + 3 = \pm \sqrt{\frac{21}{2} }[/tex]

Analysis: At this level, students start analyzing and naming the properties of geometric figures.

Informal deduction: At this level pupils or students perceive relationships between properties and figures.

Deduction: At this level, students can give deductive geometric proofs. They are able to differentiate between necessary and sufficient conditions.

All tick marks are equally spaced on each number line below. Find the unknown value (x) for
each. Be prepared to explain your reasoning.

Answers

By finding the value between consecutive tick marks, we will see that:

1) x = 20

2) x = 48

3) x = 9.5

How to find the values of X?

We know that each tick mark are equally spaced in the number lines below.

If you look at the first one (the already solved one). You can see that between the 4 and the 12 there are 4 ticks. If each tick has a value of T, we must have:

4 + 4*T = 12

4*T = 12 - 4 = 8

T = 8/4 = 2

Each tick values 2 units.

Between the 12 and the x there are 4 ticks, then:

x = 12 + 4*2 = 20

Now let's look at the second number line. There are 10 ticks between 25 and 140, then:

25 + 10*T = 140

10*T = 140 - 25 = 115

T = 115/10 = 11.5

And there are 2 ticks between 25 and the x, so:

x = 25 + 2*T = 25 + 2*11.5 = 48

x = 48.

Now the final number line. There are 8 ticks between 10 and 12, then:

10 + 8*T = 12

8*T = 12 - 10 = 2

T = 2/8 = 1/4 = 0.25

Now, the x is 2 ticks before the 10, then we have:

x = 10 - 2*T = 10 - 2*0.25 = 9.5
