Sales figures show a positive relationship between temperature and ice cream consumption: as temperature increases, ice cream consumption also increases. Other research shows a positive relationship between temperature and crime rate (Cohn & Rotton, 2000. When the temperature increases, both ice cream consumption and crime rates tend to increase. As a result, there is a positive correlation between ice cream consumption and crime rate. However, what do you think is the true relationship between ice cream consumption and crime rate? Specifically, what value would you predict for the partial correlation between the two variables if temperature were held constant?

To determine

To explain: The true relationship between ice-cream consumption and crime rate and also predict about the partial correlation assuming temperature is constant.

Explanation

Given info:
