   1. Probabilistically
   2. Statistically
   3. Linearly
   4. Logically

Question No:-12

Potential source of errors in RBI analysis regarding data quality are the following except

   1. If the base line thickness were not performed the nominal thickness may be used for the original thickness
   2. If original thickness not available, averaged at thickness readings may be used
   3. If the original thickness not available, maximum at thickness readings may be used

Question No:-13

Potential source of errors in RBI analysis regarding data quality are the following except

   1. Assumptions in equipment history
   2. Outdated drawings and documentation
   3. Inspector error
   4. Advanced inspection methods

Question No:-14

The following assumption can be made that significantly impact the calculated corrosion rate early in the equipment life

   1. If the base line thickness were not performed the nominal thickness may be used for the original thickness
   2. If original thickness not available, averaged at thickness readings may be used
   3. If the original thickness not available, maximum at thickness readings may be used

Question No:-15

________________ may result in the calculated corrosion rate appearing artificially high or low.

   1. Clerical error
   2. Measurement error
   3. Inspector error
   4. At scanning

Question No:-16

The data validation step stresses the need for a knowledgeable individual.

   1. To comparing data from the inspections to the expected deterioration mechanism and rates
   2. To compare the results with previous measurements on that system

   2. A metallurgist and corrosion specialist
   3. A metallurgist only
   4. Corrosion specialist only

Question No:-19

_________ are the primary inputs into the probability of failure evaluation.
