    It is quite a lengthy document. Perhaps you can show some of your thoughts, and post your doubts in a more concise manner?

    Those three problems are related to the statistical use of the normal distribution. Have you had that material already?

    Yes I have read the material. The answer I just got for question 13 was 429 grams. Is that correct?
