Question: A linear model was constructed to model the response variable weight (g) for the eggs of albatrosses (a large sea bird) based on the location

A linear model was constructed to model the response variable weight (g) for the eggs of albatrosses (a large sea bird) based on the location of the albatross nest. There were four island locations for the nests: Gough Island, Inaccessible Island, Nightingale Island, and Tristan de Cunhua. These were coded as G (Gough), I (Inaccessible), N (Nightingale) and T (Tristan de Cunhua). This produced the following linear equation: Egg weight = 286.7 + 13.3(I) - 5.7(N) + 7.9(T)

The same linear model from above was produced using different data (so please not the different beta-values!) and produced the following equation: Egg weight = 271 + 10.5(I) - 6.5(N) + 24.9(T) Calculate the average weight of an albatross egg on Nightingale Island.
