GPA was self-reported (scale 0 – 4.0). Enter the data shown here into SPSS to assess whether there is a positive relationship between grit and...

To measure profitability, La Quinta used operating margin, which is the ratio of the sum profit, depreciation, and interest expenses divided by total revenue.

La Quinta defines profitable inns as those with an operating margin in excess of 50 percent; unprofitable inns are those with margins of less than 30 percent. After a...
