QUESTION 8 In a case of `failure-terminated lifetime testing, 15 failures are observed in a total operation time T = 98.2 hrs. Assume that the failure times are independent Exponential random variables with mean µ. You seek to conduct a chi-square test of the hypotheses HO: μ = 9 H1: μ< 9. What is the observed value of the test statistic Xobs? (give answers correct to 3 decimal places) QUESTION 9 In a case of `failure-terminated lifetime testing, 15 failures are observed in a total operation time T = 178.2 hrs. Assume that the failure times are independent Exponential random variables with mean µ. You seek to conduct a chi-square test of the hypotheses HO: μ = H1: μ> 9. Evaluate the p-value of the test.
