Construct a 96% confidence interval to estimate the population proportion with a sample proportion equal to 0.36 and a sample size equal to 100. Click the icon to view a portion of the Cumulative Probabilities for the Standard Normal Distribution table A 95% confidence interval estimates that the population proportion is between a lower limit of (Round to three decimal places as needed) and an upper limit of
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...
