Homework 09: Problem 1 Previous Problem Problem List Next Problem (1 point) The 82.57% confidence interval estimate for ,u was (18.88, 26.62). Find the point estimate and the margin of error (ME) from this interval estimate. Point estimate = ME: Homework 09: Problem 2 Previous Problem Problem List Next Problem (1 point) A statistics practitioner took a random sample of 60 obsenlations from a population whose standard deviation is 27 and computed the sample mean to be 100. Note: For each confidence interval, enter your answer in the form (LCL. UCL). You must include the parentheses and the comma between the confidence limits. A. Estimate the population mean with 95% condence. Confidence Interval = B. Estimate the population mean with 90% confidence. Confidence Interval = C. Estimate the population mean with 99% confidence. Confidence Interval = Homework 09: Problem 3 Previous Problem Problem List Next Problem (1 point) A statistics practitioner took a random sample of 45 observations from a population and computed the sample mean to be 96. Note: For each confidence interval, enter your answer in the form (LCL, UCL). You must include the parentheses and the comma between the confidence limits. A. Suppose the population standard deviation is 30. Estimate the population mean with 95% confidence. Confidence Interval = B. Suppose the population standard deviation is 49. Estimate the population mean with 95% confidence. Confidence Interval = C. Suppose the population standard deviation is 7. Estimate the population mean with 95% confidence. Confidence Interval =
