A veterinary graduate student is studying the relationship between the weight of one year-old golden retrievers in pounds (y) and the amount of dog food the dog is fed each day in pounds (x). A random sample of 10 golden retrievers yielded the following data and summary statistics.
a) Write the estimated regression line below.
b) On the graph below, sketch the sample regression line using the information above. Be sure to label and scale your axes correctly.
c) What is your estimate of the average change in weight associated with a 1-pound increase in daily intake of dog food? d) What weight would you predict for a randomly selected golden retriever who is fed 1.2 pounds of dog food per day?
e) The value of s_e is 4.860. Interpret s_e in the context of this problem.
