Question: Feeding behavior of blackbream fish. In Brain and Behavior Evolution (April 2000), Zoologists conducted a study of the feeding behavior of blackbream fish. The zoologists recorded the number of aggressive strikes of two blackbream fish feeding at the bottom of an aquarium in the 10-minute period following the addition of food. The next table lists the weekly number of strikes and age of the fish (in days).
(a) Write the equation of a straight-line model relating number of strikes (y) to age of fish (x).
(b) Fit the model to the data using the method of least squares and give the least squares prediction equation.
(c) Give a practical interpretation of the value of β^0, if possible.
(d) Give a practical interpretation of the value of β^1, if possible.
