In each of the following cases, find an interval that contains approximately 95.44 percent of all the possible sample proportions. (a) p=,5, n = 250 (Round your answers to 4 decimal places. Do not round any intermediate calculations.) p(p-hat) 20(p-hat) |
(b) p= 1, n = 100 (Round your answers to 2 decimal places. Do not round any intermediate calculations.) P(p-hat) + 20(p-hat)
(c) p .8, n= 400 (Round your answers to 2 decimal places. Do not round any intermediate calculations.) 01:39:37 (p-hat) 20(p-hat)
(d) p= .98, n = 1,000 (Round your answers to 4 decimal places. Do not round any intermediate calculations.) (p-hat) 20(p-hat)
