The student will select the appropriate distributions to use in each case.
The student will conduct hypothesis tests and interpret the results.
Television survey
In a recent survey, it was stated that Americans watch television on average four hours per day. Assume that
$\sigma =2$ . Using your class as the sample, conduct a hypothesis test to determine if the average for students at your school is lower.
${H}_{o}$ :
${H}_{a}$ :
In words, define the random variable. __________ =
The distribution to use for the test is:
Determine the test statistic using your data.
Draw a graph and label it appropriately.Shade the actual level of significance.
Graph:
Determine the p-value:
Do you or do you not reject the null hypothesis? Why?
Write a clear conclusion using a complete sentence.
Language survey
About 42.3% of Californians and 19.6% of all Americans over age 5 speak a language other than English at home. Using your class as the sample, conduct a hypothesis test to determine if the percent of the students at your school that speak a language other than English at home is different from 42.3%.

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.
