Question

Each month, Nadeem keeps track of the number of times he visits the library and the number of books he checks out. Is there a correlation if you model his data with a linear equation? Is there a causal relationship?

Group of answer choices (SELECT ONE)
A. There is a positive correlation and a causal relationship.
B. There is neither a correlation nor a causal relationship.
C. There is a causal relationship but no positive correlation.
D. There is a positive correlation and no causal relationship. Other factors may influence the number of books Nadeem checks out."

Answer 1

There is a positive correlation between the number of library visits and the number of books checked out by Nadeem each month, but no causal relationship can be established.

Step-by-step explanation:

The question asks whether there is a correlation and a causal relationship between the number of library visits and the number of books checked out by Nadeem each month. A correlation measures the strength and direction of the relationship between two variables. A causal relationship implies that one variable directly affects the other.

In this case, a positive correlation may exist if the number of library visits and the number of books checked out tend to increase or decrease together. However, causality cannot be determined based on correlation alone. Other factors may influence the number of books Nadeem checks out, so it is not possible to establish a causal relationship.

Therefore, the answer is D. There is a positive correlation and no causal relationship.
