In a sample of 60 diners at a restaurant, 12 had ordered a appetizer, If the restaurant serves 800 diners each day, how many are likely to order a appetizer?
We can use proportions to solve this problem:
12 appetizers out of 60 diners is the same as x appetizers out of 800 diners.
12/60 = x/800
Cross-multiplying, we get:
60x = 9600
Dividing by 60, we get:
x = 160
Therefore, out of 800 diners, approximately 160 are likely to order an appetizer.
