A survey of 865 voters in one state reveals that 47.2% favor approval of an issue before the legislature. Construct a 95% confidence interval for the true proportion of all voters in the state who favor approval. Express the endpoints of the interval to the nearest thousandth (three decimal places). < p <

Use the given degree of confidence and sample data to construct a confidence interval for the population proportion p. Write down the confidence interval limits. Round to three decimal places. A survey of 965 voters in one state reveals that 408 favor approval of an issue before the legislature. Construct the 95% confidence interval for the true proportion of all voters in the state who favor approval. (Type your answers without any spaces between the decimal point and digits, e.g. 0.219. Round to 3 decimal places. ) ONLY round your final answer, and no other answers. The 95% confidence interval estimate is:

A survey of 573 citizens found that 317 of them favor a new bill introduced by the city. We want to find a 95% confidence interval for the true proportion of the population who favor the bill. What is the lower limit of the interval? (Round to 3 decimal digits)

In a poll of 150 randomly selected U.S. adults, 78 said they favored a new proposition. Based on this poll, compute a 95 % confidence interval for the proportion of all U.S. adults in favor of the proposition (at the time of the poll). Then complete the table below. Carry your intermediate computations to at least three decimal places. Round your answers to two decimal places. what is the lower and upper limit of the 95% confidence interval
