During every election in a particular region, pollsters conduct exit polls to determine which candidate people voted for. during the most recent election, pollsters incorrectly predicted candidate a the winner over candidate b. when asked how this error could have happened, the pollsters cited interviewer error due to the fact that since many of the interviewers were young, only young voters selected in the sample agreed to be interviewed, and young voters tended to favor candidate a. plus a computer error caused some responses to be deleted before tabulation of the results. 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 nonsampling errors led to the incorrect conclusion regarding the election select all nonsampling errors that led to the incorrect conclusion regarding the election below a. no nonsampling errors led to the incorrect conclusion in this case.
b. data-entry error is a nonsampling error that contributed to the incorrect conclusion because the errors in data entry favored candidate a.
c. nonresponse bias is a nonsampling error that contributed to the incorrect conclusion because the individuals who were selected for polling but did not respond voted differently than those who did respond to the polling.
d. interviewer error is a nonsampling error that contributed to the incorrect conclusion because the interviewers did not interview young voters.
