A report by the Association of Air Companies (ACA) indicates that the average price of plane ticket from city A to city B is 120 euros. To contrast this information is considered a random sample of 100 travelers between these two cities who flew in different companies, in which it was observed that the average of the ticket was 128 and a standard deviation of 40. Can it be considered at a significance level of 0.01 that the information from the ACA it's correct?
