For a high school female athlete strength study, the correlation between weight (pounds) and percent of body fat (BF%) equals - 0.329. Answer parts a through c below. a. Interpret the sign and the strength of the correlation between weight and body fat. Choose the correct answer below. O A. There is a positive correlation which indicates that as high school female athletes increase in weight, they tend to have less body fat. O B. There is a negative correlation which indicates that as high school female athletes increase in weight, they tend to have less body fat. O C. There is a negative correlation which indicates that as high school female athletes increase in weight, they tend to have more body fat. O D. There is a positive correlation which indicates that as high school female athletes increase in weight, they tend to have more body fat. b. Find and interpret r for weight and body fat. 12 = (Round to five decimal places as needed.) What does the value of r represent? O A. It represents the percentage of reduction in error if you predict a high school female athlete's body fat based on knowing her weight, compared to predicting the high school female athlete's body fat based on the mean body fat of all high school female athletes. O B. It represents the percentage of high school female athlete's whose body fat is more than two standard deviations away from the mean. O C. It represents the percentage of additional error if you predict a high school female athlete's body fat based on knowing her weight, compared to predicting the high school female athlete's body fat based on the mean body fat of all high school female athletes. Is the sample association strong or weak? O The association is weak. O The association is strong. c. If weight and body fat were measured instead with metric units, would any results differ in parts a and b? O Yes O No
