Let's say you want to poll a random sample of 150 students on campus to see if they prefer to take online classes. Of course, if you took an actual poll you would only get one number (your sample proportion, p-hat). Imagine all the possible samples of 150 students that you could draw and the distribution of all the possible sample proportions you would get from them.
If I told you that we know that 35% of all students actually prefer to take classes online, how would you respond to the following?:
1. Discuss the conditions necessary to use the normal curve to model this sampling distribution and explain whether or not they are met.
2. If the normal model is appropriate for this distribution, what shape would you expect it to have?
3. If you were to use the normal model for this p-hat sampling distribution, what value would be at the center of your sampling distribution? In other words, what value would all of those sample proportions center around?
4. What would be the standard deviation of this sampling distribution?
Answers
Answer:
1. Since [tex]np \geq 10[/tex] and [tex]n(1-p) \geq 10[/tex], these conditions are met.
2. Approximately normal.
3. 0.35
4. 0.0389
Step-by-step explanation:
Central Limit Theorem:
For a proportion p in a sample of size n, the sampling distribution of the sample proportion will be approximately normal with mean [tex]\mu = p[/tex] and standard deviation [tex]s = \sqrt{\frac{p(1-p)}{n}}[/tex], as long as [tex]np \geq 10[/tex] and [tex]n(1-p) \geq 10[/tex]
Let's say you want to poll a random sample of 150 students on campus to see if they prefer to take online classes.
This means that [tex]n = 150[/tex].
35% of all students actually prefer to take classes online
This means that [tex]p = 0.35[/tex]
1. Discuss the conditions necessary to use the normal curve to model this sampling distribution and explain whether or not they are met.
The conditions necessary are [tex]np \geq 10[/tex] and [tex]n(1-p) \geq 10[/tex].
We have that
[tex]np = 150*0.35 = 52.5 \geq 10[/tex]
[tex]n(1-p) = 150*0.65 = 97.5 \geq 10[/tex]
Since [tex]np \geq 10[/tex] and [tex]n(1-p) \geq 10[/tex], these conditions are met.
2. If the normal model is appropriate for this distribution, what shape would you expect it to have?
By the Central Limit Theorem, approximately normal.
3. If you were to use the normal model for this p-hat sampling distribution, what value would be at the center of your sampling distribution? In other words, what value would all of those sample proportions center around?
The mean, which by the Central Limit Theorem, is [tex]\mu = 0.35[/tex].
4. What would be the standard deviation of this sampling distribution?
By the Central Limit Theorem,
[tex]s = \sqrt{\frac{0.35*0.65}{150}} = 0.0389[/tex]

To investigate whether or not sending text messages while driving impacts driving ability, we had 100 participants (50 men and 50 women) drive an obstacle course under one of the following conditions: 1) no texting while driving, 2) sending five text messages while driving, or 3) sending 10 text messages while driving. We measured the accuracy with which the subjects drove the obstacle course from a scale of 1 to 10 (1 = poor and 10 = excellent).We are testing the effect of sending text messages at three different _____.
a. treatments
b. levels
c. factors
d. None of the above
Answers
Answer:
A - treatments
Step-by-step explanation:
We are told the 100 participants were required to drive under 1 of the 3 conditions below which are;
- no texting while driving.
- sending five text messages while driving
- sending 10 text messages while driving
In experimental a research, these 3 conditions are referred to as treatments because they are used to derive an experimental result.
