Shawna reads a scatterplot that displays the relationship between the number of cars owned per household and the average number of citizens who have health insurance in neighborhoods across the country. The plot shows a strong positive correlation. Shawna recalls that correlation does not imply causation. In this example, Shawna sees that increasing the number of cars per household would not cause members of her community to purchase health insurance. Identify the lurking...

1. A positive correlation (r = 0.52) is found between hours spent playing with other children at age two and sociability in kindergarten. Answer the following questions based on this result. a. What does a positive correlation mean in this specific scenario? b. If someone concludes that requiring children to play with others at age 2 will increase sociability, what TWO common errors of interpreting correlations are being made? c. Calculate the coefficient of determination for this scenario. d. If...
