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 = 0.036 for all calculations. The specifics can be found in the file below. Download .csv file (a) Check to see if the distribution of the fight classes appear to be normal. Hint: use a probability plot to decide with a = 0.036. A. neither direct flights nor layover flights appear to be normal OB. direct flights appear to be normal but layover fights do not appear to be normal C. Both direct flights and layover flights appear to be normal D. layover flights appear to be normal but direct flights do not appear to be normal (b) Report the p-value of the test you ran in (a) concerning the normality of first class flights, use at least two decimals in your answer. P.value = 0.011 (c) Does there appear to be a negative diference in the general price between business and first class fighta? A. No OB. Yes C. I don't have enough information to answer this question D. I have too much information to answer this question (d) At what level of significance would you come to a difforent conclusion? Piease use at least four digits in your answer. Give a decimal not a percentage. Significance Level - 0.1859 v buy a business class (direct) flight buy a first class (layover) flight buy a business class (layover) flight buy a first class (direct) flight buy either a first or business class flight, since the difference is negligible
