Based on the proportion observed in the sample of 50 colored pencils (2 unsharpened out of 50), we can estimate the number of unsharpened colored pencils in the basket of 300 colored pencils.
(2 unsharpened / 50 total) = (X unsharpened / 300 total)
Cross multiplying:
50X = 2 * 300
50X = 600
X = 600 / 50
X = 12
Therefore, we would expect approximately 12 colored pencils in the basket of 300 to be unsharpened.
Avery randomly selects 50 colored pencils from a basket and finds that 2 are not sharpened. If the basket contains 300 colored pencils, how many would you expect to be unsharpened?(1 point)
