Konstantinos is managing a wind farm that was recently put into operation. To determine the number of employees he needs on-call he needs to estimate the number of turbine failures in his wind farm. The turbines in his farm have been found to fail at a rate of 0.05 per year; however, they have never been used at the elevation of Konstantinos's farm, and therefore. Konstantinos believes he will learn more about their failure rate over time. Which of the following statements is true? Select one: O a. Konstantinos is describing aleatory uncertainty, which should go to zero as he learns more about the turbines in his farm at this elevation. Epistemic uncertainty will remain since there may be natural variation, but his estimate of epistemic variability will become more accurate as he gathers more data. O b. Konstantinos is describing epistemic uncertainty, which should go to zero as he learns more about the turbines in his farm at this elevation. Aleatory uncertainty will remain since there may be natural variation, and he will not get more accurate estimates of aleatory variability. Oc. Konstantinos is describing epistemic uncertainty, which should go to zero as he learns more about the turbines in his farm at this elevation. Aleatory uncertainty will remain since there may be natural variation, but his estimate of aleatory variability will become more accurate as he gathers more data. O d. Konstantinos is describing aleatory uncertainty, which should go to zero as he learns more about the turbines in his farm at this elevation. Epistemic uncertainty will remain since there may be natural variation, and he will not get more accurate estimates of epistemic variability.
