This module provides a lab on Chi-Square Distribution as a part of Collaborative Statistics collection (col10522) by Barbara Illowsky and Susan Dean. Labs changed to incorporate mini-tabs.

Class Time:

Name:

Student learning outcome:

The student will evaluate data collected to determine if they fit either a uniform distribution.

Collect the data

Three car-pooling students claimed that they missed their statistics test because they had a flat tire. On the make-up test the instructor asked them to identify the particular tire that went flat. The instructor assumed that the distribution would be uniform. To test this assumption,survey the class to determine the number the which tire they would select.

Number Selected

Hypothesis test

Conduct a hypothesis test to determine if the selection of a tire fits a Uniform Distribution.

${H}_{o}$ :

${H}_{a}$ :

Calculate the test statistic.

Find the
p-value.

Sketch a graph of the situation. Label and scale the x-axis. Shade the area corresponding to the
p-value.

State your decision.

State your conclusion in a complete sentence.

If in fact the students did not have a flat tire, do you think they will be caught out? Explain.

Questions & Answers

Is there any normative that regulates the use of silver nanoparticles?

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?
