A health researcher conducts a survey of the relation of proportion of fat in a person's diet to proportion of time the person uses a seat belt. (The idea is that those who practice one kind of health-related behavior may be more likely to practice another kind.)Here are the scores for three participants.
M = 36.67 SD = 10.27 M = 53.33 SD = 12.47 r = -.96
a. Give the Z score prediction formula for predicting seat belt usage from fat in their diet.
b. Predict the seat belt usage of a person who has 40% fat in their diet.
c. Explain what you have done to a person who is familiar with correlation but not with regression.
