Table 3E.4 contains 20 observations on cycles to failure of aluminum test coupons subjected to repeated alternating stress of 15,000 psi at 20 cycles per second. Construct a normal probability plot, a lognormal probability plot, and a Weibull probability plot for these data. Based on the plots, which distribution seems to be the best model for the cycles to failure for this material?
Answer to relevant QuestionsConsider the outpatient service times in Exercise 3.3. Construct a normal probability plot, an exponential probability plot, and a Weibull probability plot for these data. Do any of these distributions seem to be a ...Suppose that two fair dice are tossed and the random variable observed—say, x—is the sum of the two up faces. Describe the sample space of this experiment, and determine the probability distribution of x. A manufacturer of electronic calculators offers a one-year warranty. If the calculator fails for any reason during this period, it is replaced. The time to failure is well modeled by the following probability distribution: A ...A stock brokerage has four computers that are used for making trades on the New York Stock Exchange. The probability that a computer fails on any single day is 0.005. Failures occur independently. Any failed computers are ...An inspector is looking for nonconforming welds in the gasoline pipeline between Phoenix and Tucson. The probability that any particular weld will be defective is 0.01. The inspector is determined to keep working until ...
