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?
In the first survey, 18 out of 50 people said they like the clothing store the best. This means that 18/50 = <<18/50=0.36>>0.36, or 36% of people surveyed, like the clothing store the best.
If he conducts a second survey with 125 people, the best prediction for the number of people who will say they like the clothing store the best is 0.36 x 125 = 45 people. Answer: \boxed{45}.
To make the best prediction for the number of people who will say they like the clothing store the best in the second survey, we can use the concept of proportions.
In the first survey, out of 50 people surveyed, 18 said they like the clothing store the best. Therefore, the proportion of people who like the clothing store is 18/50.
To predict the number of people in the second survey who will say they like the clothing store the best, we can use this proportion.
Assuming the proportion remains the same, we can set up a proportion:
(18/50) = (x/125)
Cross-multiplying, we get:
18 * 125 = 50 * x
2250 = 50x
Dividing both sides by 50, we get:
x = 45
Therefore, the best prediction for the number of people who will say they like the clothing store the best in the second survey is 45 people.
