Question

1. Suppose failures occur at the following times (in seconds): 13, 19, 31, 38, 51, 68, 78, 95, 119, 132, 161, 189, 231, 259, 286, 301, 345, 379, 401 Characterize the above failure occurrences according to: (a) time of failure (b) time interval between failures (c) failures experienced in a time interval of 20 seconds (d) cumulative failures experienced up to 100 seconds, 280 seconds, and 350 seconds. 2. Suppose we use the error seeding model to predict the number of errors in a program. Assume that 30 errors are seeded, but only 6 seeded errors and 10 indigenous errors are found by a testing team. What is the estimated number of the remaining indigenous errors?

Characterize the above failure occurrences according to:
(a) time of failure
(b) time interval between failures
(c) failures experienced in a time interval of 20 seconds
(d) cumulative failures experienced up to 100 seconds, 280 seconds, and 350 seconds.

2. Suppose we use the error seeding model to predict the number of errors in a program. Assume that 30 errors are seeded, but only 6 seeded errors and 10 indigenous errors are found by a testing team.
