Use the given confidence interval to find the margin of error and the sample proportion. (0.783,0.807)
Use the given confidence interval to find the margin of error and the sample proportion. (0.630,0.658) E(Type an integer or a decimal.) (Type an integer or a decimal.)
Use the given confidence interval to find the margin of error and the sample proportion. (0.664,0.692) E=(Type an integer or a decimal.) Ô=(Type an integer or a decimal.)
Use the given confidence interval to find the margin of error and the sample proportion. (0.630,0.660) E= (Type an integer or a decimal.) p=(Type an integer or a decimal.)
Use the normal distribution to find a confidence interval for a proportion p given the relevant sample results. Give the best point estimate for p , the margin of error, and the confidence interval. Assume the results come from a random sample. A 95% confidence interval for the proportion of the population in Category A given that 18% of a sample of 450 are in Category A. Round your answer for the point estimate to two decimal places, and your...
Calculate a margin of error given a confidence interval Question In a questionnaire, a random sample of commuters were asked whether it takes them more than 30 minutes to commute to work in the morning. The resulting confidence interval for the proportion of commuters who drive more than 30 minutes to work in the morning is is (0.27,0.51) What is the sample proportion, p?

In clinical trials, among 4217 patients treated with the drug, 122 developed the adverse reaction of nausea. Construct a 90% confidence interval for the proportion of adverse reactions a) Find the best point estimate of the population proportion p. (Round to three...
Use the given confidence interval to find the margin of error and the sample mean. (14.6,23.8)
1. Use the confidence interval to find the estimated margin of error. Then find the sample mean. A biologist reports a confidence interval of (4.0, 4.8) when estimating the mean height (in centimeters) of a sample of seedlings. 2. In a random sample of 26 people, the mean commute time to work was 32.2 minutes and the standard deviation was 7.1 minutes. Assume the population is normally distributed and use a t-distribution to construct a 80% confidence interval for the...
