 Page 1 / 1
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

1. Record the price per pound of 8 fruits, 8 vegetables, and 8 breads in your local supermarket.
2. Explain how you could try to collect the data randomly.

## Analyze the data and conduct a hypothesis test

1. Compute the following:
• Fruit:
• $\overline{x}$ =
• ${s}_{x}$ =
• $n$ =
• Vegetables:
• $\overline{x}$ =
• ${s}_{x}$ =
• $n$ =
• $\overline{x}$ =
• ${s}_{x}$ =
• $n$ =
2. Find the following:
• $\mathrm{df\left(num\right)}$ =
• $\mathrm{df\left(denom\right)}$ =
3. State the approximate distribution for the test.
4. Test statistic: $F$ =
5. Sketch a graph of this situation. CLEARLY, label and scale the horizontal axis and shade the region(s) corresponding to the p-value.
6. p-value =
7. 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?

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

Introduction about quantum dots in nanotechnology
what does nano mean?
nano basically means 10^(-9). nanometer is a unit to measure length.
Bharti
do you think it's worthwhile in the long term to study the effects and possibilities of nanotechnology on viral treatment?
absolutely yes
Daniel
how to know photocatalytic properties of tio2 nanoparticles...what to do now
it is a goid question and i want to know the answer as well
Maciej
Abigail
for teaching engĺish at school how nano technology help us
Anassong
Do somebody tell me a best nano engineering book for beginners?
there is no specific books for beginners but there is book called principle of nanotechnology
NANO
what is fullerene does it is used to make bukky balls
are you nano engineer ?
s.
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
Mostly, they use nano carbon for electronics and for materials to be strengthened.
Virgil
is Bucky paper clear?
CYNTHIA
carbon nanotubes has various application in fuel cells membrane, current research on cancer drug,and in electronics MEMS and NEMS etc
NANO
so some one know about replacing silicon atom with phosphorous in semiconductors device?
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?
s.
how to fabricate graphene ink ?
for screen printed electrodes ?
SUYASH
What is lattice structure?
of graphene you mean?
Ebrahim
or in general

On having this app for quite a bit time, Haven't realised there's a chat room in it.
Cied
what is biological synthesis of nanoparticles
what's the easiest and fastest way to the synthesize AgNP?
China
Cied
types of nano material
I start with an easy one. carbon nanotubes woven into a long filament like a string
Porter
many many of nanotubes

what is the k.e before it land
Yasmin
what is the function of carbon nanotubes?
Cesar
I'm interested in nanotube
