select the correct answer. kristen gathered data from her classmates about the age and contents of their backpacks. she displayed the data in two scatter plots. does either scatter plot indicate a positive correlation between the variables? a. only plot a b. only plot b c. both plot a and plot b d. neither plot a nor plot b

Answer

Explanation:

Step1: Recall positive - correlation concept

In a positive - correlation, as the value of one variable increases, the value of the other variable also increases.

Step2: Analyze Plot A

In Plot A, as the backpack age (x - variable) increases, the total number of pens and pencils (y - variable) does not show a clear upward trend. There is no consistent increase.

Step3: Analyze Plot B

In Plot B, as the number of pencils (x - variable) increases, the number of pens (y - variable) does not show a clear upward trend. There is no consistent increase.

Answer:

D. neither plot A nor plot B
