1. Prepare a simple regression of Operating Expenses as a function of Revenue passengers carried. |
Prepare a plot of the regression results. Include in your XY scattergram a trendline, R2, and regression |
formula. Be sure the regression formula is not in scientific notation. Please note that JetBlue shows |
Operating expenses in $millions and revenue passengers in thousands. I suggest, for ease of interpretation, |
that you convert one of the two amounts such that they are stated in the same denomination. |
For example, JetBlue reports 2019 Operating expenses as $7,294 million. I converted operating expenses |
for my analysis to thousands, with the amount after conversion being $7,294,000 thousand. |
Be sure your regression line exactly intersects the axis (either Y or X, whichever it may be). |
2. Prepare a simple regression of Operating revenues as a function of Revenue passengers carried. |
Prepare a plot of the regression results. Include in your XY scattergram a trendline, R2, and regression |
formula. Be sure the regression formula is not in scientific notation. Please note that Operating |
revenues is shown in $millions. I suggest, for ease of interpretation, making the same adjustment to |
Revenue passengers as I recommend in #1. |
Be sure your regression line exactly intersects the axis (either Y or X, whichever it may be). |
3. Prepare a simple regression of Operating expenses as a function of an average number of departures. |
Prepare a plot of the regression results. Include in your XY scattergram a trendline, R2, and |
regression formula. Be sure the regression formula is not in scientific notation. Again please note |
that Departures are the actual number, they are not summarized in thousands or millions. |
4. In other words, I recommend restating Departures into thousands, for example, I restated 2019 Departures |
of 368,355 to 369. |
5. Using the regression equations derived in #1 and #2, estimate the number of Revenue passengers to |
be carried for JetBlue to break even. Subtract the Operating expense equation from the |
Operating revenues equation, plugging in Revenue passengers carried until the result is $0. That will |
be your break-even point, on average, over the years 2010 - 2019? |
6. I am sure you noticed the negative intercepts in two of your regression equations? This can be explained |
through a concept referred to as the "relevant range" in a regression formula. Would you please explain the |
regression intercepts using the "relevant range" definition? |
