Textbook Question
Chapter 5, Problem 36E
Rivets A company that manufactures rivets believes the shear strength (in pounds) is modeled by N(800, 50).
- a) Draw and label the Normal model.
- b) Would it be safe to use these rivets in a situation requiring a shear strength of 750 pounds? Explain.
- c) About what percent of these rivets would you expect to fall below 900 pounds?
- d) Rivets are used in a variety of applications with varying shear strength requirements. What is the maximum shear strength for which you would feel comfortable approving this company’s rivets? Explain your reasoning.

Is there sufficient evidence to support the claim that there is a linear correlation between the weights of bears and their chest sizes?
