Then round your answers as indicated. A) The margin of error is: Round your answer to the nearest hundredth sit-ups B) The corresponding 95% confidence interval for the true population mean is: When setting confidence intervals for discrete data investigators will round the lower endpoint down to the next lowest integer and the upper endpoint up to the next highest integer. You should express your answers using this convention to 6. -12 points My Notes Acrylic bone cement is sometimes used in hip and knee replacements to fix an artificial joint in place. The force required to break an acrylic bone cement bond was measured for n - 20 specimens under specified conditions, and the resulting mean and standard deviation were 302.09 Newtons and 40.37 Newtons, respectively. Assuming that the breaking force under these conditions has a distribution that is approximately normal, construct a 95% confidence interval for the true average breaking force, f of the acrylic bone cement under the specified conditions. Note: you should carry at least 5 decimal precision for any intermediate calculations then round your answer as indicated in the problem newtons Note: Round your these endpoints to the nearest whole number Submit Assignment Save Assignment Progress Home My Assignments Extension Requesf webAss°18 4 0 1997-2017 Advanced Instructional Systems, Inc Al rights reserved. 2:19 PM 10/24/20172 Type here to searchExplanation / Answer
