For mallard ducks and Canada geese, what percentage of nests aresuccessful (at least one offspring survives)? Studies in Montana,Illinois, Wyoming, Utah, and California give the followingpercentages of successful nests (Reference: The Wildlife SocietyPress, Washington, D.C.). x: Percentage success for mallard ducknests 11 23 44 53 65 y: Percentage success for Canada goosenests 39 15 48 15 39 (a) Use a calculator to verify that Σx= 196; Σx2 = 9,620; Σy = 156; and Σy2 = 5,796. Σx Σx2 Σy Σy2 (b)Use the results of part (a) to compute the sample mean, variance,and standard deviation for x, the percent of successful mallardnests. (Round your answers to two decimal places.) x s2 s (c) Usethe results of part (a) to compute the sample mean, variance, andstandard deviation for y, the percent of successful Canada goosenests. (Round your answers to two decimal places.) y s2 s (d) Usethe results of parts (b) and (c) to compute the coefficient ofvariation for successful mallard nests and Canada goose nests.(Round your answers to one decimal place.) x y CV % % Write a briefexplanation of the meaning of these numbers. What do these resultssay about the nesting success rates for mallards compared to Canadageese? The CV is the ratio of the standard deviation to the mean;the CV for Canada goose nests is higher. The CV is the ratio of thestandard deviation to the mean; the CV for Canada goose nests isequal to the CV for mallard nests. The CV is the ratio of thestandard deviation to the mean; the CV for mallard nests is higher.The CV is the ratio of the standard deviation to the variance; theCV for Canada goose nests is higher. The CV is the ratio of thestandard deviation to the variance; the CV for Canada goose nestsis equal to the CV for mallard nests. The CV is the ratio of thestandard deviation to the variance; the CV for mallard nests ishigher. Would you say one group of data is more or less consistentthan the other? Explain. The x data group is more consistentbecause the standard deviation is smaller. The two groups areequally consistent because the standard deviations are equal. The ydata group is more consistent because the standard deviation issmaller.
