A state conducts a study that shows strong negative correlation between residents' life expectancy and number of breweries within 2 miles of the residents. The state concludes that if they mandate a decrease in the number of breweries life expectancy will go up. Select all true statements and explain why.
A. The state's conclusion is correct as long as the correlation measures strong linear association with no distorting outliers.
B. We can use this study to conclude that proximity to breweries causes life expectancy to decrease.
C. There may be a lurking variable that explains this association.
D. As long as the study was done on random and independent residents, and shows strong negative correlation with no distorting outliers, we can conclude that there is an association between life expectancy and proximity to breweries.

Two major automobile manufacturers have produced compact cars with the same size engines. We are interested in determining whether or not there is a significant difference in the MPG (miles per gallon) of the two brands of automobiles. A random sample of eight cars from each manufacturer is selected, and eight drivers are selected to drive each automobile for a specified distance.
