I need help on a homework problem.
For the most recent year available the mean annual cost to attend a private university in the United States was $20,182. Assume the distribution of annual costs follows a normal probability distribution and the standard deviation is $4,400. Ninety-nine percent of all students at private universities pay less than what amount?
