The student will calculate the 90% confidence interval for proportion of students in this school that were born in this state.

The student will interpret confidence intervals.

The student will determine the effects that changing conditions have on the confidence interval.

Collect the data

Survey the students in your class, asking them if they were born in this state. Let
$X$ = the number that were born in this state.

$n$ =
$\text{\_\_\_\_\_\_\_\_\_\_\_\_}$

$x$ =
$\text{\_\_\_\_\_\_\_\_\_\_\_\_}$

Define the Random Variable
$\hat{p}$ in words.

State the estimated distribution to use.

Find the confidence interval and error bound

Calculate the confidence interval and the error bound.

Confidence Interval:

Error Bound:

How much area is in both tails (combined)?
$\alpha $ =

How much area is in each tail?
$\frac{\alpha}{2}$ =

Fill in the blanks on the graph with the area in each section. Then, fill in the number
line with the upper and lower limits of the confidence interval and the sample proportion.

Describe the confidence interval

In two to three complete sentences, explain what a Confidence Interval means (in general), as
if you were talking to someone who has not taken statistics.

In one to two complete sentences, explain what this Confidence Interval means for this
particular study.

Using the above information, construct a confidence interval for each given confidence
level given.

Confidence level

ME / Error Bound

Confidence Interval

50%

80%

95%

99%

What happens to the ME as the confidence level increases? Does the width of the
confidence interval increase or decrease? Explain why this happens.

Questions & Answers

anyone know any internet site where one can find nanotechnology papers?

fullerene is a bucky ball aka Carbon 60 molecule. It was name by the architect Fuller. He design the geodesic dome. it resembles a soccer ball.

Tarell

what is the actual application of fullerenes nowadays?

Damian

That is a great question Damian. best way to answer that question is to Google it. there are hundreds of applications for buck minister fullerenes, from medical to aerospace. you can also find plenty of research papers that will give you great detail on the potential applications of fullerenes.

Tarell

what is the Synthesis, properties,and applications of carbon nano chemistry

Yeah, it is a pain to say the least. You basically have to heat the substarte up to around 1000 degrees celcius then pass phosphene gas over top of it, which is explosive and toxic by the way, under very low pressure.

Do you know which machine is used to that process?
