A recent study by the Greater Los Angeles Taxi Drivers Association showed that the mean fare charged for services from Hermosa Beach to Los Angeles International Airport is $ 22 and the standard deviation is $ 3.40. We select a sample of 22 fares. What is the likelihood that the sample mean is between $ 21 and $ 23? Assume the population of fares is normally distributed. (Round z value to 2 decimal places and final answer to 4 decimal places )
