Problem 2

The test effort during the software testing phase, such as human resources,the number of test cases, and CPU time, can be measured by the cumulativeamount of testing effort during the time interval (0, t]. Yamada et al. [YAMA1986] proposed a formula for W(t): dW (t)/dt = g(t)(1 W(t)) where g(t) is theinstantaneous consumption rate of the testing effort expenditures. W(t) is definedas W(t) = t0 w(t)dt where w(t) is the testing-effort consumption rate at time t.Find an explicit expression for W(t) in terms of g(t) and show that W(t) is theRayleigh distribution.
