Submitting incomplete or inaccurate opscan forms will be subject to a 5 point test grade penalty. Be sure you have entered the following and darkened the appropriate circles: NAME STUDENT ID NUMBER=student ID number TEST CODE= test form (A in this case) TEST ID= CRN 5. Fill in the opscan answers as you work through the test, do not wait until the proctor calls time/pencils down. Students will be required to stop working immediately, including opscan marking, when time/pencils down is called. You have 60 minutes to complete the test. 6. Multiple choice problems with only one answer are clearly marked. For other problems, follow the individual problem instructions. 7. Check your test to make sure you have 11 printed pages in the booklet. If you are missing any page, notify a proctor. 8. Show all work in the test booklet, even for the multiple choice questions.

Imagine that a member of your team agreed to a schedule of team meeting times but has missed the last three meetings without notifying another team member. You want to give this team member feedback. Assume that you have already negotiated a good time to talk. Write a script, like the one we did in lecture, for providing feedback to this team member. (6 points total). 15. In one paragraph, provide one specific example of how Conor demonstrated engaging in problem formulation as he described his plan to return to Nepal and find the seven children and return them to their homes. Be specific and provide details from The Little Princes to demonstrate your point.

The data will contain positive, negative, and zero values which you need to track for your analysis. Prepare a flowchart for an algorithm that will store all the positive values in one vector, the negative values in a second vector, and will count the number of zero values. This algorithm will have 3 outputs: 1) the vector of positive data values, 2) the vector of negative zero values, and 3) the number of zero values. (15 points)
