A company that manufactures rivets believes the shear strength (in pounds) is modeled by N(750,30). Use the 68–95–99.7 Rule to complete parts a) through c) below. a) Draw and label the Normal model. b) Would it be safe to use these rivets in a situation requiring a shear strength of 720 pounds? Explain. Choose the correct answer below. A. No, because about 32% of all of this company's rivets have a shear strength of less than 720 pounds. B. Yes, because very nearly all of this company's rivets have a shear strength of more than 720 pounds. C. No, because about 16% of all of this company's rivets have a shear strength of less than 720 pounds. D. Yes, because only about 2.5% of all of this company's rivets have a shear strength of less than 720 pounds. c) About what percent of these rivets can be expected to fall below 810 pounds?
