Answered

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?



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 = 0.30*2000 = 600 people in the entire school are estimated to name sports drink as their favorite.

Another way to solve

54/180 = x/2000

54*2000 = 180x

x = 54*2000/180

x = 600
