Question

e 1o.1 waldite Mallarnd Drucks anud Camada Geese For mallard ducks and Canuda geese, what percentage of nests are successful (at least one offspring ines)? Studies in Montana, Ilinois, Wyoming. Utah, and California gave the following percentages of successful nests (Reference: Sociery Press, Washington, D.C.). he Wildtlife x: Percentage success for mallard duck nests 56 85 5213 39 y: Percentage success for Canada goose nests 24 53 6069 18 (a) Use a calculator to verify that Ex 245. x 14,755: Sy 224: and 2 = 12,070. (b) Use the results of part (a) to compute the sample mean, variance, and standard deviation for x, the percent of successful mallard nests. (c) Use the results of pat (a) to compute the sample mean, variance, and standard deviation for y the percent of successtul Canada goose nests, (d) Interpretation Use the results of parts (b) and (c) to compute the coef ficient of variation for successful mallard nests and Canada goose nests. Write a brief explanation of the meaning of these numbers. What do these results say about the nesting success rates for mallards compared to those of Canada geese? Would you say one group of data is more or less con- sistent than the other? Explain.
