Question:The data table (in Excel format) contains the historical air traffic data from the Houston Intercontinental Airport (IAH). Specifically, it lists the top 13 air travel markets (in terms of passenger volume) from IAH. For each market (for example, Houston (IAH) - Dallas (DFW)), the table shows not only the total passenger volume, but also the breakdown by airlines (carriers).

I dont know how to use formulas in excel to calculate this and I need help with:

  1. calculate the Index of Dissimilarity (ID) and
  2. calculate the Gini's Coefficient (G) for each market
  3. and identify the market with the highest level of competition.
