In a Study of Diet, the Amount of Weight Lost

Multiple Choice

In a study of diet, the amount of weight lost and the starting weight for each individual was recorded. A scatterplot of the data is provided. The correlation between weight lost and starting weight was computed to be 0.934.
Because the correlation between starting weight and weight lost is so high, what can we conclude?

A) Having a high starting weight will cause a person to lose a lot of weight.
B) The slope of the least-squares regression line will be much larger than 1.
C) There is a strong, positive linear association between starting weight and weight lost, but this association may be largely driven by an influential observation.
D) Approximately 93% of the variability in weight lost is due to a person's starting weight.
