From sample data collected, we want to see if any relationship exists between specific products and the color in which they were ordered. The table below shows the number of times each product was ordered in each color. A chi-square test of independence will help to determine whether a relationship exists between product and color.

	Product A	Product B	Product C
Black	30	40	50
Red	10	58	22
Silver	60	35	10

Is there a relationship between product and color, using α = .05?

You want to see if there is a relationship between how anxious someone is and their favourite colour. You assume that people who like colours like red or orange are more likely to be anxious than those who like colours like blue or green. From your population, 50 percent report liking red or orange and 50% report liking blue or green. You then give them an anxiety test. Anxiety scores range from 0-25 (0 being the lowest, 25 being the highest...
