Question

in a public opinion poll 624 people from a sample of 1100 indicated they would vote for specific candidate how many votes can the candidate expect to receive from a population of 40000

Answer 1

Hello!

In a sample of 1100 people, the specific candidate got 624 votes. So, we can write it as 624/1100.

And if the total of voters is 40,000, how many votes this specific candidate will receive? We can write it as x/40,000.

Now, let's equal both fractions look:

`\begin{gathered} (624)/(1100)=(x)/(40000) \\ \\ 1100x=624*40000 \\ 1100x=24960000 \\ x=(24960000)/(1100) \\ \\ x\cong22691 \end{gathered}`

Answer:

Approximately 22691 votes.
