1. A cereal company advertises that “there is a cup of raisins in each box of Raisin
Surprise.” Recently, the boxes of Raisin Surprise you have purchased seem not to have
very many raisins in them, and you hypothesize that there are fewer raisins per box than
the company claims. After contacting the cereal company, you find that they claim that
the mean is 1.00 cups of raisins per box with a standard deviation of 0.22. You randomly
select 50 boxes of Raisin Surprise and measure the raisin content. You find that your
sample has a mean of 0.93 cups of raisins. Do the results of your investigation support
your hypothesis? Explain your answer. Assume a = 0.05 (1-tailed).
