Based on hospital records the standard deviation for the recovery time after ACL surgery is 8 days. You are testing out a new ACL surgery and want to find a 99% confidence interval for the mean recovery time. You perform ACL surgery with this new technique on 38 randomly selected patients and find that they averaged 36 days for recovery and had a standard deviation of 7 days. Round your answers to two decimal places. A. The sampling distribution follows a distribution. B. With 99% confidence the mean recovery time for all patients who will receive this surgery is between and . C. If many groups of 38 randomly selected Americans were surveyed, then a different confidence interval would be produced from each group. About percent of these confidence intervals will contain the true population mean number of days for recovery and about percent will not contain the true population mean number of days for recovery
