Annual income in dollars New York 48205, 49959, 56823, 49383, 46878, 44282, 47622, 46516, $7321, 52102, 51762, 42289, 51587, 55176, 45878 Illinois 54099, 43487, 42438, 41940, 40871, 38783, 46709, 41399. 37590, 40647. 54173, 48386, 48379, 46382, 50093 Send data to calc... v Send data to Excel The population standard deviations for the annual incomes of childcare workers in New York and in Illinois are estimated as 6600 and 6200, respectively.
