Question

The city of Raleigh has 10300 registered voters. There are two candidates for city council in an upcoming election: Brown and Feliz. The day before the election, a telephone poll of 250 randomly selected registered voters was conducted. 80 said they'd vote for Brown, 151 said they'd vote for Feliz, and 19 were undecided.

Give the sample statistic for the proportion of voters surveyed who said they'd vote for Brown. Note: The proportion should be a fraction or decimal, not a percent.

    

This sample statistic suggests that we might expect     of the 10300 registered voters to vote for Brown.

Explanation / Answer

80 said they will vote for Brown out of 250 registered voters.

proportion of voters who said they will vote for Brown is 80/250 = 0.32

This sample statistic suggests that we might expect  0.32*10300 = 3296   of the 10300 registered voters to vote for Brown.
