Question
The data to the right compare the on-time arrival performance of two airlines, X and Y. The table shows the status of 13,423 arrivals for one year. Complete parts (a) through (c) below. Airline X Airline Y On time 6,121 5,090 Delayed 1,138 1,074 Does it appear that a lurking variable might be at work here? How can you tell? Select the correct choice below and, if necessary, fill in the answer boxes to complete your choice. CA. Yes, because the on-time rate for flights to Denver is 85.3 %, whereas the on-time rate for flights to Philadelphia is 84.6 %. This is important since most of airline X's flights go to Denver, whereas most of airline Y's flights go to Philadelphia. (Round to one decimal place as needed.) O B. Yes, because the on-time rate for flights to Dallas is %, whereas the on-time rate for flights to Minneapolis is %. This is important since these two cities have the fewest number of flights. (Round to one decimal place as needed.) O C. Yes, because there appears to be association in each of the given tables. O D. No, because there is no apparent pattern in the data. (c) Each cell of the following table shows the number of on-time arrivals for each airline at each destination. Dallas Denver Minneapolis Philadelphia Airline X 393 5,073 335 320 Airline Y 513 492 168 3,917 Is the destination a lurking factor behind the original 2x2 table? Select the correct choice below and fill in the answer boxes to complete your choice. (Round to one decimal place as needed.) O A. Yes, because airline Y has a better on-time arrival rate in Dallas ( % for X vs. % for Y) and in Minneapolis ( % for X vs. % for Y). O B. Yes, because airline Y has a better on-time arrival rate in Denver ( % for X vs. % for Y) and in Philadelphia ( % for X vs. % for Y) O C. No, because airline X has a better on-time arrival rate in Denver ( % for X vs. % for Y) and in Philadelphia ( % for X vs. % for Y). O D.
