A real estate agent believes that property taxes average $6,500 on new homes, locally. She selects 40 new home sales at random, and in this sample the average property taxes were $6,560. The standard deviation of the population is $120. Test her belief at a = 0.10. (To get full credit you must show all parts of the hypothesis test, including the conclusion you reach about her belief.)
