Choose a variable. Before collecting the data, decide what a likely average might be, then complete the following:
a. Write a brief statement of purpose of the study
b. Define the population
c. State the hypotheses for the study
d. Select an a value
e. State how the sample was selected
f. Show the raw data
g. Decide which statistical test is appropriate and compute the test statistic (z or t). Why is the test appropriate?
h. Find the critical values(s)
i. State the decision
j. Summarize the results.
You may obtain raw data from the random number table in the appendix section of your text or from any other sources, including sources on the World Wide Web.
The solution determines the variable analysis for data collections.
