What is the percentage price change for a zero coupon bond if its YTM changes from 3.9% to 4.6%? The bond's face value is $1,000 and it matures in 8 years. Use the price determined from the first yield, 3.9%, as the base in the percentage calculation. Round to the nearest tenth of a percent. (e.g., 4.32% = 4.3). ​[Hint: If the price dropped, enter a negative number].

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 11 23 44 53 65 y: Percentage success for Canada goose nests 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 mallard nests. (Round your answers to two decimal places.) x s2 s (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 two decimal places.) y s2 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 y 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? 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 the standard deviation to the mean; 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 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. 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. The y data group is more consistent because the standard deviation is smaller.

A particular poll tracks daily the percentage of citizens from a certain country who approve or disapprove of the job the President is doing. Daily results are based on telephone interviews with approximately 1400 national adults. The poll reported that 50​% of adults approve of the President doing his job. A media outlet claimed the true proportion to be 52​%. Does the poll contradict this​ claim? Complete parts a through c. ​a) Test the appropriate hypothesis. Find a 95​% confidence interval for the sample proportion of adults in the country who approved of the​ President's performance. Check conditions. Which conditions for the confidence interval have been​ met? Select all that apply. A. ​Success/Failure Condition B. ​10% Condition C. Randomization Condition Let p be the proportion of adults in the country who approved of the​ President's performance. What are the null and alternative​ hypotheses? Upper H 0​: p ▼ greater than equals less than not equals nothing vs. Upper H Subscript Upper A​: p ▼ equals greater than less than not equals nothing ​(Type integers or decimals. Do not​ round.) Find the 95​% confidence interval. left parenthesis nothing comma nothing right parenthesis ​(Round to three decimal places as​ needed.) ​b) Does your confidence interval provide evidence to contradict the​ claim? Select the correct choice below and fill in the answer box to complete your choice. ​(Type an integer or a decimal. Do not​ round.) A. Since nothing is within the​ interval, the confidence interval does not provide evidence that contradicts the media​ outlet's claim. B. Since nothing is within the​ interval, the confidence interval provides evidence that contradicts the media​ outlet's claim. C. Since nothing is not within the​ interval, the confidence interval provides evidence that contradicts the media​ outlet's claim. D. Since nothing is not within the​ interval, the confidence interval does not provide evidence that contradicts the media​ outlet's claim. ​c) What is the significance level of the test in​ b? Explain. Select the correct choice below and fill in the answer box to complete your choice. ​(Type an integer or a decimal. Do not​ round.) A. The significance level is alphaequals nothing because the test is a​ two-tail test based on a 95​% confidence interval. B. The significance level is alphaequals nothing because the test is a​ one-tail test based on a 95​% confidence interval. C. The significance level is betaequals nothing because the test is a​ two-tail test based on a 95​% confidence interval. D. The significance level is betaequals nothing because the test is a​ one-tail test based on a 95​% confidence interval.

For each employee listed, use both the wage-bracket method and the percentage method to calculate the federal income tax withholding. Refer to Appendix A, 2017 and Appendix 2018 Federal Tax Tables. I need to see the step by step for both 2017 Tax Table calculation and the 2018 Tax Table calculation.

Thank you!
