![Testing for Independence
The contingency table shows the results of a random sample of adults with respect to
their ages and favorite fast food restaurant. At the significance level, a=0.01, test the
claim that at least two of the variables are dependent.
Use the Independence #1 calculator to test the hypothesis. Fill in the contingency table
for row and columns based on the results. Also fill in the space for the level of
significance a
