For each of the following pairs of variables, indicate whether you would expect a positive correlation, a negative correlation, or a correlation dose to 0. Explain your choice. . 1. Price and weight of an apple
a. There is a positive correlation, because the cost of produce is determined by its weight, so a heavier apple would cost less.
b. There is a positive correlation, because the cost of produce is determined by its weight, so a heavier apple would cost more.
c. There is a negative correlation, because the cost of produce is determined by its weight, so a heavier apple would cost more.
d. There is a negative correlation, because the cost of produce is determined by its weight, so a heavier apple would cost less.
e. There is a correlation close to 0, because the cost of produce is not related to its weight, so there no reason to believe a heavier apple would cost more.
2. A person's height and the number of pets he or she has
a. There is a positive correlation, because taller people have more pets.
b. There is a positive correlation, because taller people have fewer pets.
c. There is a negative correlation, because taller people have more pets.
d. There is a negative correlation, because taller people have fewer pets.
e. There is a correlation close to o, because there is no reason to believe that the height of a person would be at all associated with the number of pets a person has.
