Question

A simple random sample was taken of 1000 shoppers Respondents were classified by gender (male or female) and by meat department preference (beef, chicken, fish). Results are shown in the contingency table: Gender: Beef Chicken Fish Row Total Male 200 150 50 400 Female 250 300 50 600 Column Total 450 450 100 1000 Is there a difference in meat preference between males and females? The solution to this problem takes four steps: (1) state the hypotheses, (2) formulate an analysis plan, (3) analyze sample data, and (4) interpret results. Use a 0.05 level of significance. Χ2 = (200 - 180)2/180 + (150 - 180)2/180 + (50 - 40)2/40 + (250 - 270)2/270 + (300 - 270)2/270 + (50 - 60)2/60 Χ2 = 400/180 + 900/180 + 100/40 + 400/270 + 900/270 + 100/60 Χ2 = 2.22 + 5.00 + 2.50 + 1.48 + 3.33 + 1.67 = 16.2 As you can see, the math gets a bit cumbersome, so I did it for you! h. What will the distribution look like on a Bell curve? I need help with letter H. I understand all the rest.
