A new pump is in its first reliability demonstration test. Of concern to management is its reliability over an initial warranty period consisting of the first 50 cycle.Fifteen unitswere tested for 300 cycles with five failures occurring at cycle times 51, 82, 135, 186, 277.Assuming an exponential distribution, calculate the reliability during the warranty period, i.e., R(50)
