Many people believe that crime rate declines with age a) Use the data below to verify whether this is true using a scatterplot b) Is the relationship between crime rate and age strong, medium, or weak? c) Can the correlation coefficient be used to measure the extent to which crime rate is related to age? E Click the icon to view the data a) Choose the correct scatterplot below. OA. OB. OC. OD. 20,000- 8 20.000- 8 20 000 8 20.000 Age Age Does it appear that the crime rate declines with age? O A. The crime rate tends to gradually increase with age. O B. The crime rate tends to increase until adulthood, after which it gradually declines. OC. The crime rate tends to increase until middle age, after which it gradually declines O D. The crime rate tends to gradually decrease with age. b) Is the relationship between crime rate and age strong, medium, or weak? O A. The scatterplot appears to show a medium relationship. O B. The scatterplot appears to show a weak relationship. OC. The scatterplot appears to show a strong relationship. O D. The scatterplot appears to show no relationship. c) Can the correlation coefficient be used to measure the extent to which crime rate is related to age? O A. No, because the Linearity Condition is not met. O B. No, because the Outlier Condition is not met. OC. Yes, because all of the correlation conditions are met.
