Question

Spring is a peak time for selling houses. The file "Spring Houses" contains the selling price, number of bathrooms, square footage, and number of bedrooms of 26 homes sold in Ft. Thomas, Kentucky, in spring. Determine if the correlation coefficient r is positive or negative, and what this suggests about the relationship between two variables.

Answer 1

The correlation coefficient, r, measures the strength of the linear association between two variables. A positive value of r indicates a positive correlation, suggesting that as one variable increases, the other variable tends to increase as well.

Step-by-step explanation:

The correlation coefficient, r, measures the strength of the linear association between two variables. A positive value of r indicates a positive correlation, which means that as one variable increases, the other variable tends to increase as well. In this case, since spring is a peak time for selling houses, we can expect that as the selling price of houses increases, the number of bathrooms, square footage, and number of bedrooms may also increase.
