Normal or random variations that are considered part of operating the system at its current capability are : a. systemic variations. b. special cause variations. c. common cause variations. d. life cycle variations

Normal or random variations that are considered part of operating the system at its current capability are c. common cause variations.

Explanation:

Common cause variation is fluctuation caused by unknown factors resulting in a steady but random distribution of output around the average of the data.

Common-cause variation is the natural or expected variation in a process.

Common-cause variation is characterised by:

It is a measure of the process potential, or how well the process can perform when special cause variation removed.

Common cause variation arises from external sources that are not inherent in the process and is where statistical quality control methods are most useful.

Statistical process control charts are used when trying to monitor and control 5- and 6-sigma quality levels.

answer; i believe its compare (b3: b4) ;

solution:

this situation is called an ip conflict.

data from a server is sent in small bits called packets. in an ip conflict, some packets will end up in one computer while some other packets will end up in another computer.

so…overall none of the computers get the data as the original message or picture being sent by the server cannot be retrieved with only half the packets. so it will show up as an error.

thus the final answer is d.
