So, choice A?
Choice A?
From 30 students, 20 students ask for chocolate =30/20=1.5
From 1500 students, how many students will like chocolate =1500/1.5=1000
Answer is =1000 or option A
To determine how many of the 1500 students in the school most likely prefer chocolate ice cream based on Barry's results, we can use proportional reasoning.
Step 1: Calculate the percentage of students who prefer chocolate ice cream in Barry's sample.
To do this, divide the number of students who prefer chocolate ice cream (20) by the total number of students in Barry's sample (30) and multiply by 100:
(20/30) * 100 ≈ 66.67%
Step 2: Apply the percentage to the total number of students in the school.
To estimate the number of students who most likely prefer chocolate ice cream, multiply the percentage calculated in Step 1 (66.67%) by the total number of students in the school (1500):
(66.67/100) * 1500 = 1000
Therefore, based on Barry's results, it can be estimated that approximately 1000 students in the school most likely prefer chocolate ice cream.
