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.
Questions & Answers
I only see partial conversation and what's the question here!
what about nanotechnology for water purification
please someone correct me if I'm wrong but I think one can use nanoparticles, specially silver nanoparticles for water treatment.
