Suppose a brand of cereal claims that each box contains 7% marshmallows and 93% flakes. You think that value is too high so you collect so you'd like
to test their claim. You'd like to prove there are fewer marshmallows than
that. You found that out of 600 pieces of cereal only 29 of them were
marshmallows. Assuming all conditions are met to perform a significance
test, state the null and hypothesis. Then, staſe the p-value and make a
conclusion based on a 5% significance level.
