Refer to the Financial Management (Spring 1995) study of 49 firms filing for prepackaged bankruptcies, Exercise 2.32 (p. 62). Recall that three types of "prepack" firms exist: (1) those who hold no prefiling vote, (2) those who vote their preference for a joint solution; and (3) those who vote their preference for a prepack.
a. Construct a box plot for the time in bankruptcy (months) for each type of firm.
b. Find the median bankruptcy times for the three types.
c. How do the variabilities of the bankruptcy times compare for the three types?
d. The standard deviations of the bankruptcy times are 2.47 for "none," 1.72 for "joint," and 0.96 for "prepack." Do the standard deviations agree with the interquartile ranges with regard to the comparison of the variabilities of the bankruptcy times?
e. Is there evidence of outliers in any of the three distributions?
