Question.21 A health research institute wants to estimate the minimum average recovery time in weeks for patients who undergo a new kind of surgical procedure. They collect a sample of 41 patients and document their recovery times. The sample mean recovery time is calculated to be 7 weeks, and the sample standard deviation is 1.2 weeks. Determine the lower one-sided 95% confidence bound for the population mean recovery time. Assume the recovery time follows a normal distribution.
