In the Focus Problem at the beginning of this chapter, a study was described comparing the hatch ratios of wood duck nesting boxes. Group I nesting boxes were well separated from each other and well hidden by available brush. There were a total of 465 eggs in group I boxes, of which a field count showed about 270 hatched. Group II nesting boxes were placed in highly visible locations and grouped closely together. There were a total of 806 eggs in group II boxes, of which a field count showed about 276 hatched. (a) Find a point estimate p̂1 for p1, the proportion of eggs that hatch in group I nest box placements. (Round your answer to three decimal places.) p̂1 = Find a 95% confidence interval for p1. (Round your answers to three decimal places.) lower limit upper limit (b) Find a point estimate p̂2 for p2, the proportion of eggs that hatch in group II nest box placements. (Round your answer to three decimal places.) p̂2 = Find a 95% confidence interval for p2. (Round your answers to three decimal places.) lower limit upper limit (c) Find a 95% confidence interval for p1 − p2. (Round your answers to three decimal places.) lower limit upper limit

Two competing airlines, Alpha and Beta, fly a route between Des Moines, Iowa, and Wichita, Kansas. Each airline claims to have a lower percentage of flights that arrive late. Let p1 be the proportion of Alpha's flights that arrive late and p2 the proportion of Beta's flights that arrive late. Suppose that p1=0.32 and p2=0.22. Find the probability that a sample of 100 flights for each airline (200 in all) would yield p̂1≥p̂2. Round your answer to four decimal places....

Independent random samples of n1 = 900 and n2 = 900 observations were selected from binomial populations 1 and 2, and x1 = 120 and x2 = 150 successes were observed. (a) What is the best point estimator for the difference (p1 − p2) in the two binomial proportions? p̂1 − p̂2 n1 − n2     p1 − p2 x1 − x2 (b) Calculate the approximate standard error for the statistic used in part (a).

In the Health ABC Study, 546 subjects owned a pet and 1967 subjects did not. Among the pet owners, there were 297 women; 988 of the non-pet owners were women. Find the proportion of pet owners who were women. Do the same for the non-pet owners. (Be sure to let Population 1 correspond to the group with the higher proportion so that the difference will be positive. Round your answers to three decimal places.) p̂1 = p̂2 = (b) Give...

One difficulty in measuring the nesting success of birds is that the researchers must count the number of eggs in the nest, which is disturbing to the parents. Even though the researcher does not harm the birds, the flight of the bird might alert predators to the presence of a nest. To see if researcher activity might degrade nesting success, the nest survival of 102 nests that had their eggs counted, was recorded. Sixty-four of the nests failed (i.e. the...

Question #1 For this problem, carry at least four digits after the decimal in your calculations. Answers may vary slightly due to rounding. Santa Fe black-on-white is a type of pottery commonly found at archaeological excavations at a certain monument. At one excavation site a sample of 602 potsherds was found, of which 370 were identified as Santa Fe black-on-white. Let p represent the proportion of Santa Fe black-on-white potsherds at the excavation site. Find a point estimate for p....
