Assume you are a psychologist studying the relationship between chocolate consumption and happiness. You ask 10 participants to rate how much chocolate (in ounces) they ate in the last week, and how happy they felt throughout the week on the average, on a scale ranging from 1 (extremely unhappy) to 10 (extremely happy). You hypothesize that there is some relationship between chocolate consumption and happiness. Here are their scores:

Participant #	Chocolate eaten during week (oz)	Happiness rating
1	5	3
2	6	9
3	3	7
4	7	6
5	4	4
6	6	8
7	10	1
8	6	7
9	2	1
10	1	4
