For each of the following, indicate whether you would expect a positive correlation, a negative correlation, or zero correlation. a) The age of an individual and the incidence of heart attacks.
b) The hand with which a person writes and the IQ of the individual
c) The quantity of acid rain that falls and the quantity of fish that a lake has.
d) The height of an individual and the incidence of cancer
e) Annual income and educational level
f) Hours of physical activity per week and body fat percentage.

a) positive correlation

b) no correlation

c) positive correlation

d) no correlation

e) positive correlation

f) positive correlation

Step-by-step explanation:

a) positive

b) no correlation

c) negative

d) no correlation

e) positive

f) negative

Step-by-step explanation:

A: The older you are, the more likely you are to have a heart attack (when one goes up, the other goes up) so positive

B: IQ is based on logic/reasoning not physical characteristics like their dominant hand. These two things are unrelated so there shouldn't be a correlation

C: The more acid rain there is, the more fish will die, so there will be less fish (when one goes up the other goes down) so that would be negative

D: I'm not a doctor or anything, but I think cancer risks come from the things you're exposed to or if it runs in your family, which is unrelated to height.

E: If you have a college education you should be able to get a higher paying job. More education = higher income so positive

F: The more someone excersises, they are likely to have less fat so that would be negative

.there can be infinite values of m and n that can satisfy the above equation. for each value of m of m or n. there maybe infinite sets of solution for the above
