Answer #1

a) The correlation between the number of calories consumed and a person's weight is most likely to be positive because if a person consumed more calories, their weight increases.

b) Cannot be a correlation - As both of the variables (age of a child and the number of pets owned) seem to be unrelated to each other.

c) Negative - As the number of hours spent partying increases, the GPA might reduce

d) Negative - As the age of the car increases, the resale value will decrease

e) Positive - As the person's age increases, the experience increases and the income increases too

f) Positive - As the average temperature increases, the weather is hotter and hence the icecream sales might increase.
