Concept explainers
Refer to Exercise 8.36. An engineer observes n = 10 independent length-of-life measurements on a type of electronic component. The average of these 10 measurements is 1020 hours. If these lengths of life come from an exponential distribution with mean θ, estimate θ and place a 2-standard-error bound on the error of estimation.
8.36 If Y1, Y2, … , Yn denote a random sample from an exponential distribution with mean θ, then E(Yi) = θ and V (Yi) = θ2. Thus,
