Question

In a random sample of 100 voters, 48 said they planned on voting for the Republican presidential candidate. On election day, 51% of voters actually voted for the Republican presidential candidate. (a) Identify the value of the sample proportion.

Answer 1

Answer: 0.48 .

Explanation:

• The sample proportion is a ratio of number of successes in a sample to the sample size.

Let p be the proportion of voters actually voted for the Republican presidential candidate.

Given: In a random sample of 100 voters, 48 said they planned on voting for the Republican presidential candidate.

Sample proportion:
`\hat{p}=(48)/(100)=0.48`

Hence, the sample proportion is 0.48 .
