Answer 1

Given information:

400 random voters

155 - voted for Brown

Find: number of voters who will vote for Brown if 10,500 voters are surveyed.

Solution:

As we can see in the picture, the proportion of voters who said they'd vote for Brown is 0.3875.

To determine the actual number of voters who will vote for Brown if 10,500 voters are surveyed with the same proportion of 0.3875, we will simply multiply 10,500 by 0.3875 and then round off the answer to the nearest whole number.

`10,500*0.3875=4,068.75\approx4,069`

Answer:

We might expect 4, 069 of the 10,500 registered voters to vote for Brown.
