What are the chances your flight will leave on time To the r

What are the chances your flight will leave on time? To the right are a histogram and summary statistics for the percentage of flights departing on time each month from 2001 thru 2006. There is no evidence of a trend over time. (The correlation of On Time Departure % with time is r = 0.005.) Complete parts a) through c) below. Check the assumptions and conditions for inference. Is the independence assumption met? Is the randomization condition met or is the sample suitably representative?

Solution

The monthly ariavls are independent. So, the independent assumption is met.

The correct option is YES

Yes, the randomization condition is met.
