In a survey of 50 randomly selected families at the zoo, 15 families chose the polar bear exhibit as there favorite. If 2,000 families are at the zoo, predict how many like the polar bear exhibit?
First, we need to find the proportion of families who chose the polar bear exhibit as their favorite:
Proportion = (Number of families who chose the polar bear exhibit) / (Total number of families surveyed)
Proportion = 15 / 50
Proportion = 0.3
Next, we can use this proportion to predict how many families out of 2,000 would choose the polar bear exhibit:
Predicted number of families = Proportion x Total number of families
Predicted number of families = 0.3 x 2,000
Predicted number of families = 600
Therefore, we can predict that 600 families out of 2,000 would choose the polar bear exhibit as their favorite.
