A dog trainer is exploring the relationship between the size
A dog trainer is exploring the relationship between the size of the dog (weight in pounds) and its daily food consumption (measured in standard cups). Below is the result of a sample of 18 observations.


a. Compute the correlation coefficient. Is it reasonable to conclude that the correlation in the population is greater than zero? Use the .05 significance level.
b. Develop the regression equation for cups based on the dog’s weight. How much does each additional cup change the estimated weight of the dog?
c. Is one of the dogs a big undereater orovereater?
