What are the expected and observed counts?
A biologist is studying the composition of birds on a lake and counts 61 ducks, 17 geese, 11 cranes, 15 swans, and 6 herons. From previous studies performed around the same time of the year, she expects 50% of the birds to be ducks, 23% to be geese, 12% to be cranes, 10% to be swans, and 5% to be herons. What are the expected and observed counts? Select one.

Expected = 55 ducks, 25 geese, 13 cranes, 11 swans, and 6 herons |
|
Expected = 55 ducks, 25 geese, 13 cranes, 11 swans, and 6 herons |
|
Expected = 61 ducks, 17 geese, 11 cranes, 15 swans, and 6 herons |
|
Expected = 61 ducks, 17 geese, 11 cranes, 15 swans, and 6 herons |
