kacy surveyed 20 students at his middle school and 13 of them had at least 1 sibling
there are 300 students at kacy middle school
if the rest of the school is consistent with these results about how many students would have at least one student
Based on the survey, we can estimate that 65% (13 out of 20) of students have at least one sibling.
To estimate how many students in the entire school have at least one sibling, we can use this percentage:
65% of 300 students = 0.65 * 300 = 195
Therefore, we can estimate that about 195 students at Kacy Middle School have at least one sibling.
