1) Suppose we were interested in exploring the relationship between loneliness and depression as were Quellet and Joshi (1986). I obtain 5 participants and measure both their loneliness scores (designated variable X) and their depression scores (designated Y). The results are presented below: Higher scores represent higher levels of the measure.

Calculater for the data below. Your correlation should round to a 10th decimal place (e.g.,r = 0.10,r =0.20,r = 0.30, etc...)

Loneliness (X)	Depression (Y)
4	16
27	34
18	33
7	23
31	26

2) Carroll and Shmidt (1992) hypothesized that having a good sense of humor may be related to good physical health. Sense of humor is measured using the Situation Humor Response Questionnaire (Martin & Lefcourt, 1984). Physical health is measured by having participants fill out a self-report inventory on health problems. Scores are represented below - Higher scores represent higher levels of the measure.

Calculate the slope (b₁) for the data below. Your answer should round to the nearest 10th decimal (e.g., b₁ = 0.10, b₁ = 0.20, b₁ = 0.30, etc...) Remember, that b₁can be negative.

(hint: retain as many decimals as possible while doing your calculations to ensure that rounding error doesn't bias your final value)

Humor (X)	Health (Y)
36	9
68	18
61	16
51	17
