This is an actual problem from the 1997 AdvancedPlacement Statistics Examination. It is stated here because itrelates to concepts presented in Chapter 12. (Problem #4, 1997AP).
A random sample of 415 potentialvoters was interviewed before the start of a state-wide campaign forgovernor; 223 of the 415 said they favored the new candidate over theincumbent. However, the new candidate made several unfortunateremarks one week before the election. Subsequently, a new randomsample of 630 voters showed that 317 voters favored the newcandidate.
