Question

the scatterplot of the housing cost index versus the median family income for 10 states is shown on the right. the correlation is 0.646. complete parts a) through e). if we standardize both variables, what would the correlation coefficient between the standardized variables be? a. there is a moderate positive linear association with a few outliers. b. there is a moderate negative linear association with a few outliers. c. there is a strong association but it is not linear.

Explanation:

Step1: Recall property of correlation coefficient

Standardizing variables does not change the correlation coefficient between them.

Step2: Use given correlation value

The original correlation is 0.646, and after standardizing, it remains the same.

Answer:

0.646
