For mallard ducks and Canada geese, what percentage of nests are successful (at least one offspring survives)? Studies in Montana, Illinois, Wyoming, Utah, and California give the following percentages of successful nests (Reference: The Wildlife Society Press, Washington, D.C.). x: Percentage success for mallard duck nests 44 80 44 17 38 y: Percentage success for Canada goose nests 63 33 21 45 36 USE SALT (a) Use a calculator to verify that Ex=223; Ex² = 12,005; Ey = 198; and Ey² = 8,820. Ex Ex² Ey² Ey s² s (b) Use the results of part (a) to compute the sample mean, variance, and standard deviation for x, the percent of successful mallard nests. (Round your answers to four decimal places.) x (c) Use the results of part (a) to compute the sample mean, variance, and standard deviation for y, the percent of successful Canada goose nests.
