A manufacturer of watches would like to examine preferences for digital versus analog watches. A sample of n=200 people is selected, and these individuals are classified by age and preference. The manufacturer would like to know whether there is a relationship between age and watch preference. The observed frequencies (fo) are as follows:

	Digital	Analog	Undecided	Totals
Younger than 30	90	40	10	140

30 or older	10	40	10	60

Column totals	100	80	20	n=200

a. Conduct all 6 steps of appropriate statistic. Be sure to label all six steps.

b. Calculate and interpret the effect size for this test.

c. Report the statistics as you would in a journal article.
