The SAS output above display parameter estimate from fitting a Poisson loglinear model using x = 1 (light color) or 0 (dark color) and Y = number of satellites 1. Report the prediction equation 2. Estimate the mean of Y for female crabs with light color (x = 1). Also estimate the mean of Y for female crabs with dark color (x = 0). Comment on these values. 3.
