The
hypothesis test itself has an established process. This can be summarized as follows:
 Determine
${H}_{o}$ and
${H}_{a}$ . Remember, they are contradictory.
 Determine the random variable.
 Determine the distribution for the test.
 Draw a graph, calculate the test statistic, and use the test statistic to calculate the
pvalue . (A zscore and a tscore are examples of test statistics.)
 Compare the preconceived
$\alpha $ with the pvalue, make a decision (reject or do not reject
${H}_{o}$ ), and write a clear conclusion using English sentences.
Notice that in performing the hypothesis test, you use
$\alpha $ and not
$\beta $ .
$\beta $ is needed to help
determine the sample size of the data that is used in calculating the pvalue. Rememberthat the quantity
$1\beta $ is called the
Power of the Test . A high power is desirable. If the
power is too low, statisticians typically increase the sample size while keeping
$\alpha $ the same.
If the power is low, the null hypothesis might not be rejected when it should be.

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.
