Question

home Craig randomly surveys 50 people to find their favorite store at the mall . He finds that 18 people say they like the clothing store the best. If he conducts a second survey with 125 people, which is the best prediction for the number of people who will say they like the clothing store the best?

Answer 1

Solution

For this case we cna solve the problem using a proportional rule like this:

$\frac{18}{50}=\frac{x}{125}$

And solving for x we got:

$x=125\cdot\frac{18}{50}=45$

then the final solution for this case would be 45
