Question

From the choices below, what is the most plausible value for the correlation between spending on tobacco and spending on alcohol (all data points are considered)? A. 0.99 B. 0.8 C. 0.08 D. -0.8 Correlation 3 points is a measure of the direction and strength of the linear (straight-line) association between two quantative variables. The analysis of data from a study found that the scatterplot between two variables, x and y appeared to show a straight-line relationship and the correlation was calculated to be -0.84. This tells us that A. there is little reason to believe that the two variables have a linear relationship B. all of the data values for the two variables lie on a straight line. C. there is a strong linear relationship between the two variables with larger values of x tending to be associated with large values of the variable. D. there is a strong relationship between x and y with smaller x values tending to be associated with values of the y variable. E. there is a weak linear relationship between x and y with smaller x values tending to be associated with smaller values of the y variable.

Explanation / Answer
