4. You reach into your pocket and feel an object against your fingers. Without looking at it, you recognize the object as a coin. Which part of this example represents sensation, and which part represents perception? (3 pts)

7. How is neuronal communication like a toilet? Describe one principle of action potentials and how it relates to the toilet analogy. (1 pt extra credit)

Write a Java program that uses a Stack to: Push 5 integers onto the Stack. Display the top element. Remove the top two elements. Display the remaining Stack. Also state the time complexity of each Stack operation and the overall program. Write your answer in the below box. Points: Push 5 integers onto the Stack. (5 points) Display the top element (1 points) Remove the top two elements (1 points) Display the remaining Stack. (1 points) State the time complexity of the Stack operations. (3 points) State the overall time complexity of the program. (2 points)

P4a. Calculate the standard deviation of the final clearance, Y. Round your answer to two decimal places.

P2a. Based on the fitted Gage R&R model, the relatively small Operator variance indicates that the operators generally measure the parts similarly; therefore, differences among operators are not an important source of measurement-system variation in this study.

P1b. What percentage of the total observed variance is attributable to the measurement system? Round your answer to the nearest whole percent. Enter the number only (for example, enter 25 rather than 25%).

Q13. A stable manufacturing process is monitored using an X̄- and S-chart with subgroups of size n = 5. The Phase I study produced the following results: Lower specification limit (LSL) = 19.50 mm Upper specification limit (USL) = 20.50 mm Grand mean = 20.30 mm Average subgroup standard deviation, S̄ = 0.120 mm c4 = 0.9400 Calculate the actual process capability, Cpk. Round your final answer to two decimal places.

A process is producing measurements that all fall within the customer’s specification limits. Therefore, the process is in statistical control.

P3a. Because the overall average bias in the calibration study is approximately zero, there is no evidence of a systematic accuracy problem with this measurement system.

A stable process has Cp = 1.50 and Cpk = 0.85. Which statement best describes the process?
