1. The Excel file Atlanta Airline Data provides arrival and taxi-in time statistics for one day at Atlanta Hartsfield International Airport. 0. Find the mean and standard deviation of the difference between the scheduled and actual arrival times and the taxi-in time to the gate. 1. Compute the z-scores for each of these variables. 2. Examine the z-scores you computed for the Atlanta Airline Data. Do they suggest any outliers in the data?

I want to know the excel codes and the results for calculating outliers
