A subspecies of the Bar-tailed godwit (Limosa lapponica baueri) is a large, long-billed, long-legged and strongly migratory bird. It migrates across the Pacific Ocean from Alaska to Aotearoa, New Zealand, a longer migration than any other bird. To prepare for this long distance flight, the godwits need fuel. Their fuel (food) is predominantly marine polychaete worms, which they extract from muddy sediments using their long bills. They also eat small bivalves and crabs. In a study, a sample of 173 (79 males and 94 females) bar-tailed godwits were weighed after fuelling. The males weighed 400 grams on average and females were 600 grams on average. (i) Describe in one or two sentences what the sample for this study is. (ii) Describe in one or two sentences what a reasonable population for this study is.
