Question

You are an associate of the American Coffee Producers Association and operate small coffee shops in southern Nevada. The coffee business is quite competitive and small companies must compete with coffee giants like Starbucks. Therefore, it is important that you understand your local market demographics. One demographic you wish to study is whether there are differences in coffee consumption levels among various age groups. Understanding any relationship between age and coffee consumption will help tailor effective promotional issues. You develop and administer a survey in your target market area. Two of the questions on the survey ask 1) the respondent's age range and 2) the respondent's level of daily coffee consumption. The results of the survey are shown in the table below. Perform the appropriate test at alpha = .05 to determine if the level of daily coffee consumption is related to customer age.  Note: this problem required the use of Minitab for step 3. Please could attach the file of the Minitab picture. Thank you!

Respondent's Age Group:

Daily Consumption Level:; < 30 Years; 30 to < 40 Years; 40 < 50 Years; 50 and Older;

Low (less than 2 cups) 36; 15; 10; 26

Moderate (2 to 3 cups) 32; 30; 24; 24

High (more than 3 cups) 21; 27; 20; 22
