Question

toby put equal sized marbles into a bowl. then, he shook the bowl until 8 marbles fell out. is this sample of the marbles likely to be biased? yes no

Explanation:

When marbles are equal - sized and the bowl is shaken, the 8 marbles that fall out are a random sample. A biased sample would be one where certain marbles are more likely to be chosen due to factors like size, shape, or position manipulation. Since there's no such manipulation here, the sample is not likely to be biased.

Answer:

no
