Dave surveyed a hundred students at his school and discovered that 41 of them owned multiple pets. Assuming this sample accurately represents the entire student population, how many of the 570 students at Dave's school own multiple pets? Round to the nearest whole number.

Answer 1

0.41 × 570 = 5.7+228 = 234.

Explanation:

If the 100 students are an accurate sample

(not a random sample, but chosen by first asking all 570 students the question and choosing 100 to reflect the proportion, and assuming they didn't change their answers and didn't lie)

then 41% of students have multiple pets so 0.41×570=234 have multiple pets.
