In a statistics class at Penn State University, a group working on a project recorded the time it took each of 20 students to drink a 12-ounce beverage and also recorded body weights for the students. Which of these statistical techniques would be the most appropriate for determining if there is a statistically significant relationship between drinking time and body weight? (Assume that the necessary conditions for the correct procedure are met.)
A) Compute a chi-square statistic and test to see if the two variables are independent.
B) Compute a regression line and test to see if the slope is significantly different from 0.
C) Compute a regression line and test to see if the slope is significantly different from 1.
D) Conduct a paired difference t-test to see if the mean difference is significantly different from 0.

To determine if there is a statistically significant relationship between two quantitative variables, such as drinking time and body weight, computing a regression line and testing if the slope is significantly different from 0 is the most appropriate method. This approach assesses the strength and direction of the relationship between the variables.
