(b) A 98% confidence interval for based on n = 11 observations with unknown. (c) A 90% confidence interval for a population proportion based on n = 11 observations (d) A 92% confidence interval based on n = 14 observations for the slope parameter
Construct a confidence interval of the population proportion at the given level of confidence. x = 540, n= 1200, 95% confidence The lower bound of the confidence interval is (Round to three decimal places as needed.)
3. A 95% confidence interval for a population proportion yielded the interval (.245, .355). Compute the margin of error. Compute the sample proportion. Will a 99% confidence interval be wider or narrower? Explain why or why not.
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...
