USA Todayreported on preferred types of office communication by different age groups. Suppose a random sample of 500 from each generation was selected and asked about their preferred method of office communication. The results are shown in Table 1. Is there evidence that the distribution of communication preference is independentacross age groups?

Table 1. Office Communication by Age Group

	Type of Communication Preferred
Age Group	Group Meetings	Face-to-Face Meetings with Individuals	Emails	Other	TOTAL
Generation Y	180	260	50	10	500
Generation X	210	190	65	35	500
Boomer	205	195	65	35	500
Mature	200	195	50	55	500
TOTAL	795	840	230	135	2000

1. What statistical test is appropriate?

2. How many of those in Generation Y would you expect to prefer email communication if there the distribution of communication preference is the same across age groups?

3. What is the test statistic?

4.What is the critical value for= 0.01?

5.Based on the results of this test (= 0.01), there is evidencethat the distribution of communication preference is associated across age groups?
