Question

The city of Raleigh has 7,200 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. 77 said they'd vote for Brown, 151 said they'd vote for Feliz, and 22 were undecided. Give the sample statistic for the proportion of voters surveyed who said they'd vote for Brown. Round your answer to four decimal places.

Answer 1

The sample statistic for the proportion of surveyed voters who would vote for Brown is 0.3080.

Step-by-step explanation:

The sample statistic for the proportion of voters surveyed who said they'd vote for Brown in the city of Raleigh can be calculated by dividing the number of voters who indicated support for Brown by the total number of surveyed voters. In this case, 77 voters said they'd vote for Brown out of a total of 250 surveyed voters. The calculation is as follows:

Proportion = Number of votes for Brown / Total number of surveyed voters.
Proportion = 77 / 250
Proportion = 0.3080

Therefore, the sample statistic for the proportion of voters who said they'd vote for Brown is 0.3080, when rounded to four decimal places.
