Problem 5 Show the steps and solve manually and if there any plot do not use program Problem 5 Show the steps and solve manually and if there any plot do not use program Problem 5 A nonreplacement reliability test is carried out on 20 high-speed pumps to estimate the value of the failure rate. In order to eliminate wear failures, it is decided to terminate the test after half of the pumps have failed. The times of the first 10 failures (in hours) are 33.7, 36.9, 46.8, 56.6, 62.1, 68.6, 78.4, 79,0, 5, and 110.2. Estimate the MTTF Problem 6 replacement test with type I censoring is run for 50 hours on 30 microprocessors. Five failures occur at 12, 19, 28, 89, and 47 hours. Esimate value of the constant failure rate.

Explanation / Answer

MTTF=T/n-K(k=0 because there arent any random failures)

T=Et+(N-n)tn

=(33.7+36.9+.......110.2)+(10)(110.2)=1770.8

MTTF=1770.8/10=177.1 hrs
