2 A nonreplacement test was carried out on 100 electronic co

(2) A nonreplacement test was carried out on 100 electronic components with a known constant failure rate. The history of failures was as follows: 1st failure after 93 h 2nd failure after 1,010 h 3rd failure after 5,000 h 4th failure after 28,000 h 5th failure after 63,000 h The testing was discontinued after the fifth failure. If we can assume that the test gives an accurate estimate of the failure rate, determine the probability that one of the components would last for (a) 10 ^5 h (b) 10^6 h. In Excel, plot the results of the test with failure number on the y-axis and time on the x-axis. Notice the exponential nature of the failures. Use the last three failures to determine a constant failure rate. Solve the question using this failure rate. Include your Excel graph with your written calculations.
