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 50 83 41 29 14 y: Percentage success for Canada goose nests 51 39 63 36 60 L USE SALT (a) Use a calculator to verify that Ex = 217; Ex2 = 12,107; Ey = 249; and Ey? = 12,987. Ex 217 Ex2 12107 Ey 249 Ey2 12987 (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 43.4 $2 537.84 s 23.1913 (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. (Round your answers to four decimal places.) y $2 S (d) Use the results of parts (b) and (c) to compute the coefficient of variation for successful mallard nests and Canada goose nests. (Round your answers to one decimal place.) X CV % Write a brief explanation of the meaning of these numbers. What do these results say about the nesting success rates for mallards compared to Canada geese? O The CV is the ratio of the standard deviation to the mean; the CV for Canada goose nests is higher. O The CV is the ratio of the standard deviation to the mean; the CV for Canada goose nests is equal to the CV for mallard nests. O The CV is the ratio of the standard deviation to the mean; the CV for mallard nests is higher. The CV is the ratio of the standard deviation to the variance; the CV for Canada goose nests is higher. O The CV is the ratio of the standard deviation to the variance; the CV for Canada goose nests is equal to the CV for mallard nests. The CV is the ratio of the standard deviation to the variance; the CV for mallard nests is higher. Would you say one group of data is more or less consistent than the other? Explain. The x data group is more consistent because the standard deviation is smaller. The two groups are equally consistent because the standard deviations are equal.
