At 95% confidence, how large a sample should be taken to obtain a margin of error of 0.039 for the estimation of a population proportion? Assume that past data are not available for developing a planning value for p*. Round up to the next whole number.
At 95% confidence, how large a sample should be taken to obtain a margin of error of 0.017 for the estimation of a population proportion? Assume that past data are not available for developing a planning value for p *. Round up to the next whole number.
a. You wish to compute the 95% confidence interval for the population proportion. How large a sample should you draw to ensure that the sample proportion does not deviate from the population proportion by more than 0.12? No prior estimate for the population proportion is available. Round intermediate calculations to at least 4 decimal places and "z" value to 3 decimal places. Round up your answer to the nearest whole number.) Sample Size - b. A business student is interested...

X 8.3.52 A magazine company is planning to survey customers to determine the proportion who will renew their subscription for the coming year. The magazine wants to estimate the population proportion with 90% confidence and a margin of error equal to 10.03. What sample size is required? Click the icon to view a table of critical values for commonly used confidence levels The required sample size is customers. (Round up to the nearest whole number as needed.) edea 0 Critical...
In the planning stage, a sample proportion is estimated as P = 99/110 = 0.90. Use this information to compute the minimum sample size n required to estimate p with 95% confidence if the desired margin of error E= 0.05. What happens to n if you decide to estimate p with 90% confidence? (You may find it useful to reference the z table. Round intermediate calculations to at least 4 decimal places and "z" value to 3 decimal places. Round...
