I need help on these 2 stats questions:

Homework3: Problem 5 (1 point) Jonathan considers booking a flight to see the temple at Chichen ltza, 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 = 0.046 for all calculations. The specifics can be found in the file below. Download .csv file (a) Check to see if the distribution of the flight classes appear to be normal. Hint: use a probability plot to decide with a = 0.046. f\". A. Both direct flights and layover flights appear to be normal .5. B. neither direct flights nor layover flights appear to be normal (5 c. direct flights appear to be normal but layover flights do not appear to be normal A 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 = E (c) Does there appear to be a negative difference in the general price between business and first class flights? f\". A. I have too much information to answer this question .5. B. I don't have enough information to answer this question ff. C. Yes KN D. No (d) At what level of significance would you come to a different conclusion? Please use at least four digits in your answer. Give a decimal not a percentage. Significance Level = E (e) Based on the above calculations, to save money Jonathan should ? {D "Non Stop_Flights", "one_Stop_flights" "1", "1743.29", 1585.49 "2 " , "1486. 79", 1713.26 "3" , "1727.34", 1822.9 "4", "1374.59" , 2321.33 "5" , "1622.01", 1790.49 "6", "1700.49" , 1630.49 "7" , "1674.93" , 1693.4 "8", "1827.98", 1553.7 "9", " ", 1557.61 "10" "1 , 1591.57Homework3: Problem 6 (1 point) Does one national airline consistently leave the departure gate later than the another, or not? To determine this, random samples of 15 flights from each airline were taken on a randomly chosen weekday during the summer months (when there are no weather issues). The difference in minutes between the time the flight is to pull-away from the gate and the actual time the flight pulled away from the gate is the variable being measured, a variable called the "delay". Positive values indicate the flight was late in pulling away from the gate (negative values indicate the flight left the gate earlier than scheduled). The data is given here. Use alpha = 0.05 for all calculations below Airline A: 2.1, 4.2, 5.1, 7.1, 6.5, 7, 6, 8.7, 7.2, 6.2, 5, 6.6, 6.3, 0.3, 6.7; Airline B: 15.4, 6.9, 7.3, 2, 7.4, 6.5, 13.9, 11.1, 7, 3.1, 2.1, 0.6, 12.1, 5.8, 6.8; Download .csv file You wish to conduct a statistical test to see if there is a difference between Airlines A and B in the variable "delay". (a) Does this data indicate that the variable of interest is normally distributed? Use available technology to create the most appropriate graph or graphs. Select the statement that is closest to your findings. ,A, A. The data suggests that the variability in the delay is less for Airline A than Airline B. ,A, B. The data suggests that delay is normally distributed for Airline A and not normally distributed for Airline B. ,A, C. The data suggests that delay is not normally distributed for Airline A and not normally distributed for Airline B. A. D. The data suggests that delay is not normally distributed for Airline A and normally distributed for Airline B. ,A, E. The data suggests that the variability in the delay is the same for Airline A and Airline B. ,A, F. The data suggests that delay is normally distributed for Airline A and normally distributed for Airline B. ,A, G. The data suggests that the variability in the delay is more for Airline A than Airline B.
