graph for #5:

graph for #6:

Explanation:

Question 5:

Step1: Analyze the data relationship

Birth month is a categorical variable (not related to a numerical scale that affects test scores in a causal way). There is no logical connection between the month one is born and a science - test score.

Question 6:

Step1: Analyze the data relationship

Calories burned are related to physical activity. In a spin - class, a heavier person (assuming similar levels of activity) is likely to burn more calories because they have more mass to move. As weight (an independent variable) increases, calories burned (a dependent variable) also tends to increase.

Answer:

1. No relationship.
2. Positive relationship.
