9 10 11Figure 1Figure 2Figure 3Figure 41. For which data set is the correlation coefficient r closestto -17Choose one2. For which data set is the correlation coefficient r closestto 0?Choose one3. Which data set indicates the strongest positive linearrelationship between its two variables?Choose one

Answer 1

Remember that

The correlation coefficient r measures the strength and direction of a linear relationship between two variables on a scatterplot

so

Part 1 ------> Figure N 2 (negative slope)

Part 2 ----> Figure 4 (there are no relationship)

Part 3 ----> Figure 3 (positive slope)
