Question: Paul was trying to analyze the results of an experiment on the effects of music on plant growth, but he kept facing unexpected data. He was using automated instrumentation to collect growth data on the plants at periodic time intervals. He found that some of the data points were much higher or lower than anticipated, and he suspected that there was noise (error) present in the data. He wanted to investigate the main source of the error in the data so that he could take corrective actions and thus minimize the impact of the error(s) on the experiment results. What is the most likely source of error that Paul might encounter in this experiment: human error, instrumentation error, or sampling error? Consider the various sources of noise (error).

Question: LO10.4Consider the dilemma you might someday face if you are the CFO of a company that is struggling to satisfy investors, creditors, stockholders, and internal company managers. All of these financial statement users are clamoring for higher profits and more net assets (also known as equity). If at some point, you suddenly found yourself not meeting the internal and external earnings and equity targets that these parties expect, you would probably search for some way to make the financial statements look better. What if your boss, the CEO, suggested that maybe you should make just one simple journal entry to record all the goods that your company is holding on consignment, as if that significant amount of goods were owned by your company? She might say that this action on your part would fix a lot of problems at once, since adding the consigned goods to merchandise inventory would simultaneously increase net assets on the balance sheetandincrease net income on the income statement (since it would decrease cost of goods sold). How would you respond to this request? Write a memo, detailing your willingness or not to embrace this suggestion, giving reasons behind your decision. Remember to exercise diplomacy, even if you must dissent from the opinion of a supervisor. Note that the challenge of the assignment is to keep your integrity intact while also keeping your job, if possible.
