Jonathan considers booking a flight to see the temple at Chichen Itza, which is near Cancun Mexico. Expedica.ca offers both business class (non-stop/direct) as well as first class flights (with a 1-stop layover). Jonathan wants to know if the prices for his options are approximately the same, or if flying first class will generally cost more. Can you help him find this out? Use a = Download .csv file 0.044 for all calculations. The specifics can be found in the file below. 0.044. (a) Check to see if the distribution of the flight classes appear to be normal.
