Suppose you’re evaluating the effect of compost types on the growth rate of ornamental trees in a public garden.  The growth rate of the ornamental trees varies with sunlight, soil drainage, and compost quality.  You have batches of 3 different types of compost and 48 ornamental trees ready for planting.  You have three available planting areas, one with plentiful sunlight and well-drained soil, one with shade and well-drained soil, one with shade and poorly-drained soil, and one with shade and well-drained soil.  Which of the following experimental approaches would prevent sunlight and soil drainage from confounding the effects of the compost type? I) Use each of the 3 compost types in a different planting area II) Use all of the compost types in one of the planting areas III) Use all three compost types in all 4 planting areas

You’re interested in learning about the typical body weight of residents in the small town where you live.  The town has only 200 residents.  You send out a questionnaire to all 200 residents asking them for their body weight in kilograms.  All 200 residents reply with the requested data.  You use the data supplied by all 200 residents to determine the typical body weight of your town’s residents.  Which of the following accurately describes the typical body weight you just determined?

Saja works hard on a Homework Assignment and fills out the worksheet on her computer, typing her responses.  The instructions for this assignment indicated in all-caps in bold more than once that the responses must be entirely handwritten. The instructions specifically warn that any assignments that fail to observe this critical requirement will receive a zero. Saja doesn’t have access to a printer at home and it’s too late to go to the University to use their printer before the deadline. She doesn’t redraw the worksheet with all text and questions on a blank piece of paper, which would have been an acceptable solution. In a panic to meet the deadline, Saja doesn’t read the instructions before completing the worksheet. Saja is surprised and upset to see a “zero” in the gradebook. She finds out when she emails Professor Bohr why she got that grade, and explains she didn’t read the instructions. Saja argues it’s just not right for her to get a “zero” instead of SOME partial credit at the very least. She offers to redo the assignment, reading the instructions this time around. Will Saja’s grade change? 

What’s your dream job? (Thanks for sharing!)

Exams and quizzes will NOT be graded unless both cameras demonstrate that phones and study aids are consistently out of reach. 

Han gets caught sharing answers with other students on Quiz 2. Han profusely apologizes, and Professor Bohr reluctantly completes the paperwork to report and provide documentation of Han’s cheating to the Academic Integrity Review Board. Reporting these academic integrity violations is part of Professor Bohr’s job requirements.  Han gets caught cheating a second time when multiple students send Professor Bohr complaints that Han bragged about getting an ‘A’ on the midterm exam after circumventing Honorlock and using ChatGPT to cheat. The students were particularly upset because they studied hard and didn’t do as well as they’d hoped. Because Han got a 100 along with a few other students who collaborated, Professor Bohr decided not to curve the grades, which negatively affected his classmates. What will happen, per the policy outlined on the syllabus? 

Students MAY turn in late Homework Assignments for a 10-point reduction in credit for each day the assignment is late.
