Determine the cross-sectional area of a regular octagon cross-section tool steel piece shown. The piece weighs 3.72 pounds. The tool steel weighs 0.284 pounds per cubic inch. Round to two decimal places.
What will be an ideal response?
Volume = 3.72/0.284 = 13.0985 cu inArea = Volume/Length = 13.0985/3.67 = 3.57 sq in

The quality-assurance program for a certain adhesive formulation process involves measuring how well the adhesive sticks a piece of plastic to a glass surface. When the process is functioning correctly, the adhesive strength X is normally distributed with a mean of 200 N and a standard deviation of 10N. Each hour, you make one measurement of the adhesive strength. You are supposed to inform your supervisor if your measurement indicates that the process has strayed from its target distribution.
a. Find P(X ? 160), under the assumption that the process is functioning correctly. b. Based on your answer to part (a), if the process is functioning correctly, would a strength of 160 N be unusually small? Explain. c. If you observed an adhesive strength of 160 N, would this be convincing evidence that the process was no longer functioning correctly? Explain. d. Find P(X ? 203), under the assumption that the process is functioning correctly. e. Based on your answer to part (d), if the process is functioning correctly, would a strength of 203 N be unusually large? Explain. f. If you observed an adhesive strength of 203 N, would this be convincing evidence that the process was no longer functioning correctly? Explain. g. Find P(X ? 195), under the assumption that the process is functioning correctly. h. Based on your answer to part (g), if the process is functioning correctly, would a strength of 195 N be unusually small? Explain. i. If you observed an adhesive strength of 195 N, would this be convincing evidence that the process was no longer functioning correctly? Explain.
