Think about what the question is asking you and then look at the answers. A positive correlation between two variables means that as the independent variable increases, the dependent variable also increases.
A)Do the number of miles run and the number of calories burned have a positive correlation? They likely do since running more uses energy and that energy burns the calories, especially to a person who weighs more.
B) Do the years of education and salary have a positive correlation? They likely do since someone with more education has more opportunities to obtain certain jobs that are more high-paying such as an engineer.
C) Do the square footage of a home and its price have a positive correlation? They likely do since the bigger the living space, it's generally more expensive to afford
D) Do the speed of a car and the time to its destination have a positive correlation? They don't because as you go faster, your time to your destination decreases, which logically makes sense since speed=distance/time
E) Do a person's height and their favorite color have a positive correlation? They don't because they are completely different topics. A short person or tall person can have any color as their favorite color.
