For mallard ducks and Canada geese, what percentage of nests are successful (at least one offspring survives)? Studies inMontana, Illinois, Wyoming, Utah, and California give the following percentages of successful nests (Reference: The WildlifeSociety Press, Washington, D.C.).x: Percentage success for mallard duck nests1174681174y: Percentage success for Canada goose nests1521425424n USE SALT(a) Use a calculator to verify that Ex = 238; Ex2 = 15,818; Ey = 156; and Ey2 = 5,922.ΣχEx²EyEy²(b) Use the results of part (a) to compute the sample mean, variance, and standard deviation for x, the percent ofsuccessful mallard nests.

What do these results say about the nesting success rates formallards 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 formallard nests.O The CV is the ratio of the standard deviation to the mean; the CV for mallard nests is higher.O 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 formallard nests.O 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.O The x data group is more consistent because the standard deviation is smaller.O The two groups are equally consistent because the standard deviations are equal.O The y data group is more consistent because the standard deviation is smallerNeed Help?Read ItWatch It
