14.26 This exercise requires the use of a computer pack- age. The article “Movement and Habitat Use by Lake Whitefish During Spawning in a Boreal Lake: Inte- grating Acoustic Telemetry and Geographic Informa-tion Systems” (Transactions of the American Fisheries
Society [1999]: 939–952) included the accompanying data on 17 fish caught in 2 consecutive years.

a. Fit a multiple regression model to describe the rela-tionship between weight and the predictors length and age. y^5 2 511 1 3.06 length 2 1.11 age

b. Carry out the model utility test to determine whether at least one of the predictors length and age are useful for predicting weight.
