The city of Raleigh has 9500 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 350 randomly selected registered voters was conducted. 112 said they'd vote for Brown, 207 said they'd vote for Feliz, and 31 were undecided. a. What is the population of this survey?
b. What is the size of the population?
c. What is the size of the sample?
d. Give the sample statistic for the proportion of voters surveyed who said they'd vote for Brown.
e. Based on this sample, we might expect how many of the 9500 voters to vote for Brown?

a. The population is represented by the registered voters of the Raleigh city

b. The population size is 9,500

c. The sample size is 350

d. The proportion of people that voted for Brown was 32% >> (112 x 100) / 350 = 32%

e. The expected number of Brown's voters is 3,040 >>  (32 x 9,500) / 100 = 3,040

Step by step explanation:

In statistics, a population includes all the dataset from the study, while a sample is represented by one or more observations obtained from this dataset. The proportion can be represented by two fractions (ratios) which are equivalent to each other. Finally, the estimated size of the total population can be estimated by multiplication of the observed ratio in the sample and the size of the population (32 % x 9,500), and then dividing this number by the total ratio value.
