A) in actual use,a Z-score greater than 2.99 implies bankruptcy within one year.
B) in actual use,a Z-score greater than 1.81 implied a 90 percent chance of bankruptcy within one year.
C) in actual use,a Z-score of less than 1.81 would predict bankruptcy within one year.
D) in actual use,a Z-score less than 2.99 meant non-bankruptcy within one year.
