Last Wednesday, a random sample of 24 students were surveyed to find how long it takes to walk from the Fretwell Building to the college of education building. The survey team found a sample mean of 12.3 minutes with a standard deviation of 3.2 minutes. assuming walking time from Fretwell to College of education are normally distribution, which of the following is the correct 95% confidence interval for the population mean of walking times.
