In a study of a particular type of fish's feeding habits, zoologists recorded the age (in days) of the fish and the number of aggressive strikes the fish made at the bottom of their aquarium after being given food. Suppose the least squares regression line (equation) to predict the number of aggressive strikes a fish makes based on its age was y-hat = 175.70 - 0.82x. Predict the number of aggressive strikes for a fish 155 days old. 48.60 19.88 20.70 302.80
