Question

Joan asked 30 randomly selected adult restaurant customers about their choice of beverages. Eighteen customers said coffee is their favorite beverage. If the restaurant serves 200 adult customers per day, estimate the number who will choose coffee to drink.
A)100
B)110
C)120
D)130

Answer 1

We can use proportions to estimate the number of customers who will choose coffee.

First, we can find the proportion of the 30 sampled customers who chose coffee:

18/30 = 0.6

We can assume that this proportion will be similar for the larger population of 200 customers:

0.6 * 200 = 120

Therefore, the estimated number of customers who will choose coffee is 120, which is option C.
