"A fast food restaurant strives to serve 80 customers per hour during its peak lunch hour.  It samples 30 shifts (i.e. 30 peak lunch hours) to determine whether it is meeting this expectation.  The sample mean is 75 customers.  The population standard deviation is known to be 10.
1. Set up a null and alternative hypothesis to test whether this sample is falling below expectations.
2. Conduct this hypothesis test at the 5% level of significance.
