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.
O A. 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 B. Yes, because the on-time rate for flights to Denver is
%, whereas the on-time rate for flights to Philadelphia is
%. 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 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.
