Question
The department of Fisheries and Wildlife conducted an experiment to study the effect of depth (X_1) and location (MN or WI) on fish biomass (Y). Data was collected on 10 different streams. A dummy variable was created for location using WI as the base. Z_MN = {1, if MN 0, otherwise The model to be used is: Y = beta_0 + beta_1 X_1 + beta_2 Z_MN + beta_3 X_1 * Z_MN + epsilon The table below gives a portion of the Minitab output. What is the predicted value of fish biomass for a depth of 16.1 in MN? If we use the dummy variable Z_MN to create separate regression lines for MN and WI, what is the predicted slope of the line for MN? Test for parallelism at alpha = 0.05. What is the test statistic of the test? What is the critical value for the test in question 6?Explanation / Answer
4. The predicted value of fish biomass for a depth of 16.1 in MN is= -578+(52*16.1)+629+(-38.4*16.1*1)=269.96.
