Phoenix has 11200 registered voters. There are two candidates for city council in an upcoming election: A and B. The day before the election, a telephone poll of 400 randomly selected registered voters was conducted. 138 said they'd vote for A, 228 said they'd vote for B, and 34 were undecided. We will assume the actual voting results will be proportional to this survey.
This voter sample suggests that we might expect ______________of the 11200 registered voters to vote for A.
Very confused, and need some clarification. Please explain answer.
