Breeders of thoroughbred horses are interested in foal weight at birth because it is an indicator of health. Is foal weight related to the weight of the mare (mother)? The accompanying data are from the paper “Suckling Behaviour Does Not Measure Milk Intake in Horses”(Animal Behaviour [ 1999]: 673– 678).
a. Construct a scatterplot of these data.
b. Compute the value of the correlation coefficient.
c. Write a few sentences describing the relationship between mare weight and foal weight that refer both to the value of the correlation coefficient and the scatterplot. |
