Answer to Question #121722 in Statistics and Probability for Jessica

Question

Sixteen student volunteers at Ohio State University drank a randomly assigned number beers. Thirty minutes later, a police officer measured their blood alcohol content (BAC) in grams of alcohol per deciliter of blood. The scatterplot displays the relationship between BAC and number of beers consumed. Suppose a mistake was found in the data: the student who supposedly drank the highest number of beers (9 beers) actually only drank 6. His BAC was recorded correctly. In a new scatterplot, how would the strength of the association appear - compared to the strength of the association shown here?

A. Roughly the same as the strength of the association shown in the above scatter plot
B. Weaker than the strength of the association shown in the above scatter plot
C. Stronger than the strength of the association shown in the above scatter plot
D. It is impossible to tell

Answer 1

C. Stronger than the strength of the association shown in the above scatter plot
