PREVIOUS ANSWERS hr The authors of a paper were interested in estimating the mean time that patients who broke a hip had to wait for surgery before and after the opening of a new hospital facility They reported that for a representative sample of 405 patients seen at this hospital before the new facility was opened the mean wait time for surgery was 31 1 hours and the standard deviation of wait times was 27 0 hours For a representative sample of 214 patients seen after the new facility was opened the mean wait time for surgery was 28 7 hours and the standard deviation of wait times was 16 2 hours LUSE SALT PECKSTAT3 12 2 033 S a Construct a 95 confidence interval for the mean wait time in hours of patients seen before the new facility was opened Enter your answer using interval notation Round your numerical values to three decimal places Interpret the previously found interval We are 95 confident that the true mean wait time of patients in this sample who were seen before the new facility was opened falls within this interval We can say that 95 of all patient wait times before the new facility was opened fall within this interval There is a 95 chance that the true mean wait time of patients in this sample who were seen before the new facility was opened falls within this interval o We are 95 confident that the true mean wait time of patients seen before the new facility was opened falls within this interval O There is a 95 chance that the true mean wait time of patients seen before the new facility was opened falls within this interval hr MY NOTES b Construct a 95 confidence interval for the mean wait time in hours of patients seen after the new facility was opened Enter your answer using interval notation Round your numerical values to three decimal places Interpret the previously found interval if untianto in this cample who were seen after the new facility was opened falls within this interval Proj 1 ompa RF Biki B Forur Projec Scr 023 0 552 Scre 023 0
