This module provides a lab of F Distribution and One-Way ANOVA as a part of Collaborative Statistics collection (col10522) by Barbara Illowsky and Susan Dean.

Class Time:

Names:

Student learning outcome:

The student will conduct a simple One-Way ANOVA test involving three variables.

Collect the data

Record the price per pound of 8 fruits, 8 vegetables, and 8 breads in your local
supermarket.

Fruits

Vegetables

Breads

Explain how you could try to collect the data randomly.

Analyze the data and conduct a hypothesis test

Compute the following:

Fruit:

$\overline{x}$ =

${s}_{x}$ =

$n$ =

Vegetables:

$\overline{x}$ =

${s}_{x}$ =

$n$ =

Bread:

$\overline{x}$ =

${s}_{x}$ =

$n$ =

Find the following:

$\mathrm{df(num)}$ =

$\mathrm{df(denom)}$ =

State the approximate distribution for the test.

Test statistic:
$F$ =

Sketch a graph of this situation. CLEARLY, label and scale the horizontal axis and shade
the region(s) corresponding to the p-value.

p-value =

Test at
$\alpha =0.05$ . State your decision and conclusion.

Decision:
Why did you make this decision?

Conclusion (write a complete sentence).

Based on the results of your study, is there a need to further investigate any of the
food groups’ prices? Why or why not?

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.

Harper

Do you know which machine is used to that process?
