Compute the 95% confidence interval estimate for the population proportion, p, based on a sample size of 100 when the sample proportion, is equal to 0.28. What is the upper bound of this confidence interval? (Round to three decimal places as needed.)
Determine the sample size n needed to construct a 95% confidence interval to estimate the population mean when sigma equals 49 and the margin of error equals 6. n=????
Determine the sample size needed to construct a 95% confidence interval to estimate the average GPA for the student population at a college with a margin of error equal to 0.2. Assume the standard deviation of the GPA for the student population is 25 The sample size needed is (Round up to the nearest integer.) Determine the sample size n needed to construct a 90% confidence interval to estimate the population proportion for the following sample proportions when the margin...
