In addition the method of selecting individuals to be interviewed led to selecting a lower proportion of female voters and candidate B was favored by females. Explain which non-sampling errors led to the incorrect conclusion regarding the election. Select all nons-ampling errors that led to the incorrect conclusion regarding the election below. A. No non-sampling errors led to the incorrect conclusion in this case. B. Data-entry error is a non-sampling error that contributed to the incorrect conclusion because the errors in data entry favored candidate A. C.
