# Sampling Methods and the Central Limit Theorem

A recent study by the Greater Los Angeles Taxi Drivers Association showed that the mean fare charged for service from Hermosa Beach to LA International Airport is $18 and the standard deviation is $3.50. We select a sample of 15 fares.

a. What is the likelihood that the sample mean is between $17 and $20?

b. What must you assume to make the above calculation?
