Question

1. (10 points) Circle the best auswer that applies: (a) (2 points) The Weibull Hazard Rate: a is the number of failures per hour b is a conditional probability e is the inverse of the reliability d is a joint probability (b) (2 points) The Bath Tub Curve is defined by : a the sum of 3 separate hazard rates b repair times of repairable systems c the Beta distribution d the Gamma distribution (c) (2 points) The Exponential distribution is a special case of a the Uniform distribution b the Normal distribution c the Gamma distribution d the Beta distribution (d) (2 points) Which distribution is bounded between 0 and 1: a Normal distribution b Gamma distribution c Beta distribution d Weibull distribution (e) (2 points) For a Hazard Rate with B>1 means a the component has a constant failure rate b the failure rate is increasing with time c the failure rate is decreasing with time d the Weibull distribution is the same as the Exponential distribution

Explanation / Answer

a) number of failures per hour

b) the sum of three seperate hazard rates

c) gamma distribution

d) beta distribution

e) the failure rate is increasing with time
