Price gouging occurs when retailers take advantage of the unfortunate circumstances of others to charge exorbitant prices for needed products. This practice frequently occurs after a significant natural disaster. Suppose an area experiences a devastating hurricane and authorities suspect price gouging occurred. The average price for a gallon of milk in the area was $2.34 prior to the hurricane. If after the hurricane a sample 10 stores finds the average price is now $3.05 with a standard deviation of $0.98, does it appear that the average price of milk increased significantly after the hurricane? State the critical value (CV), test statistic (TS), and decision from the test, and state the null hypothesis. (Useα= 0.05.)


CV = 1.8331; TS = 2.29; rejectH0: there is probably no price gouging



CV = 1.8125; TS = 0.72; fail to rejectH0: there is possibly price gouging



CV = –1.8125; TS = –0.72; fail to rejectH0: there is probably no price gouging



CV = –1.8331; TS = 2.29; fail to rejectH0: there is possibly price gouging
