Which of the Following Is FALSE

Which of the following is FALSE?

A) Better sampling designs and more sophisticated samples may well be instrumental in eliminating nonsampling errors in research. The more efficient the sample design, the less important are nonsampling errors.
B) The researcher should experience little difficulty in constraining sampling error to whatever bounds he or she desires.
C) It is somewhat paradoxical but true that the more statistically efficient the sample design, the more important nonsampling errors are likely to be.
D) Nonsampling errors arise from weaknesses in research procedure. They are likely to increase with increases in the sample size.
E) Nonsampling errors contribute more than sampling errors to total error in most surveys.
