QuestionA firm sent out a random sample of 500 shipments in a new type of heavy-duty packaging. Eighteen of them damaged upon arrival at their destinations. Is it appropriate to use the methods of this section to construct a confidence interval for the proportion of shipments in heavy-duty packaging that are damaged upon arrival? If not, explain why not. Yes No, because a sample of size 500 is not large enough. No, because either $n \hat{p}$ or $n(1-\hat{p})$ is less than 10 .
