A probability tree can be used to answer this question
P(species 2 | non-tagged) = P(species 2 and non-tagged) / P(non-tagged)
= 0.38x0.85/(0.45x0.9 + 0.38x0.85 + 0.17x0.5)
= 0.397

An island has 2 species of birds. Species 1 accounts for 45% of the birds, of which 10% have been tagged. Species 2 accounts for 55%, of which 15% have been tagged. (1) what is the probability for a randomly selected bird to be tagged? (2) If a tagged bird is selected, what is the probability that it is of species 1? (3) If a tagged bird is selected, what is the probability that it is of species 2?

A rare species of bird
A rare species of bird has been re-introduced to a national forest, and researchers have been modeling their population growth over a span of 10 years. In the equation below, the variable “Years Elapsed” represents the number of years since the birds have been re-introduced to this forest. The analysts did not include the value 0 in the model, so the values for years elapsed range from 1 to 10. (Birds) = 218.86 + 35*In(Years Elapsed) On average, every three years the...

1. (a) A certain species of bird always lays 3 eggs in the spring, but it is not guaranteed that all of the eggs it lays will hatch. Scientists think that a model for the nunber, X, of eggs that hatch has a probability distribution given by 0 where θ is a parameter to be estimated. i) Given that at least one egg hatches, determine the probability that all three eggs in a nest hatch. 2 marks...

ornithologists have determined that some species o fly over water than land because air generally rises over land and falls over water during the day. A bird with these tendencies is released from an island that is 3 km from the nearest point B on the shoreline, flies to a point C on the shoreline, and then flies along the shoreline to its nesting area D. Assume that the bird instinctively chooses a path that will minimize its energy expenditure....

Questions 4-7 relate to the paragraph below. Dr. Lee studies evolution in birds. He wants to test whether a finch-like bird on Island X in the Galapagos archipelago is a different species from the finches found on the other islands in the archipelago. Beak length is used to distinguish finches from other species of birds in the Galapagos archipelago. The mean beak length of the population of finches in the Galapagos is 2 cm; the variance of beak length in...

bird grasshopper several plant species 09 What is the predicted effect of bird presence on the survivorship or biomass of the plants? (Hint: if this question leaves you puzzled, it may help to think about feeding time. If there were no birds, would more or less plant tissue be eaten by grasshoppers?)

Resplendent quetzal (Pharomachrus mocinno) is a beautiful bird species that lives in the tropical forests of Central America. Assuming that you started a breeding program and you would like to breed resplendent quetzal to produce longer tails. You measured 50 resplendent quetzals and obtained a mean tail length of 85.4 cm. You selected 10 resplendent quetzals with longest tails as breeders. The mean tail length of the breeders is 91.2 cm. After mating, offspring of the resplendent quetzal breeders have...
