Who were against the new outlet mall?

Option A) 19 to 25

Step-by-step explanation:

In the last election, 72% of the voters were in favor of a new outlet mall and

28% were against it.

Vanessa creates random samples of the voters using the numbers 1 to 25.

So, There are 25 numbers to represent all the voters

The range of number that could be used to represent the voters who were against the new outlet mall = 28% of 25 numbers = 0.28 * 25 = 7

So, 7 numbers only  could be used to represent the voters who were against the new outlet mall.

Check the options to find which range has only 7 numbers.

A) 19 to 25 ⇒ 7 numbers  

B) 7 to 18    ⇒ 12 numbers

C) 15 to 25 ⇒ 11 numbers
