You ask 180 randomly chosen students to name their favorite beverage. There are 2,000 students in the school.



Favorite Ice Cream Flavor

Sports Drink 54

Juice 35

Soda 28

Water 63

Based on the data, how many students in your school should you predict to name sports drink as their favorite beverage?

Verified Answer :

Answer:  600

Explanation

54 people of the 180 surveyed prefer a sports drink.

That's 54/180 = 0.30 = 30% of the sample.

If the sample is representative of the population, then we should expect around 30% of the population prefers a sports drink.

30% of 2000 = 0.302000 = 600 people in the entire school are estimated to name sports drink as their favorite.

Another way to solve

54/180 = x/2000

542000 = 180x

x = 54*2000/180

x = 600
