Sixteen-year-old Michelle Portman was out driving at night near Sandusky, Ohio with her friend Katie Webster in the front passenger seat. They came to a railroad crossing with multiple tracks, where the mechanical arm had descended and warning bells were sounding. A Conrail train had suffered mechanical problems and was stopped 200 hundred feet from the crossing, where it had been stalled for close to an hour. Michelle and Katie saw several cars ahead of them go around the barrier and cross the tracks, despite the fact that Ohio’s vehicle and traffic laws prohibited this practice. Michelle had to decide whether she would do the same.
Long before Michelle made her decision, the train’s engineer (a Conrail employee) had seen the heavy Saturday night traffic crossing the tracks and realized the danger. The conductor and brakeman also understood the peril, but rather than posting a flagman who could have stopped traffic when a train approached, they walked to the far end of their train to repair the mechanical problem. A police officer had come upon the scene, told his dispatcher to notify the train’s parent company Conrail of the situation, and left.
Michelle made the decision to cross the tracks. She slowly followed the cars ahead of her. Seconds later, both girls were dead. A freight train traveling 60 miles per hour struck the vehicle broadside, killing Michelle and Katie instantly.
Michelle’s mother sued Conrail for negligence. The company argued that it was Michelle’s decision, one that violated Ohio traffic laws, which led to her death. Ohio is a comparative negligence state. Discuss both the plaintiff’s claim and Conrail’s defense. What verdict will result?

#14 . Listed below are speeds (mi/h) measured from southbound traffic on I-280 near Cupertino, CA. This simple random sample was obtained at 3:30 p.m. on a weekday. Use a 0.05 significance level to test the claim of the highway engineer that the standard deviation of speeds is equal to 5.0 mi/h. (With a 95% confidence) 62 61 61 57 61 54 59 58 59 69 60 67

Snowman Co. had the following December 31, 2017, account balances (listed in alphabetical order):

Additional information not included in the above.

The tax rate is 30%

On April 1, 2017, the company sold Division M (a component of the company), which had been unprofitable for several years. For the first 3 months of 2017, Division M had operating revenues of $25,000 and operating expenses of $33,800. The division assets had a historical cost of $80,000, had been depreciated for seven years using the straight line method, allowing for a $5,000 residual value, and a ten year life. The assets were sold for $45,000.

In the middle of December, 2017, the company incurred a material $5,500 pretax loss as a result of a flood on a river that floods once every 25 years.

During a review of the 2017 entries to ascertain what adjusting entries needed to be made, it was discovered that Legal Fees of $14,000, incurred in 2015 and associated with researching a potential patent were capitalized to the account patents in 2015. The patent was never applied for and the product idea was scrapped. In 2016 patent amortization was recorded, based on a twenty-year patent life. No amortization entry was recorded in 2017.

The company paid cash dividends of $.90 per share on its common stock. All the stock was outstanding for the entire year.

While making its December 31, 2017 adjusting entries, the company conducted an analysis of its recent favorable experience with uncollectible accounts receivable, and decided to reduce the percentage used in computing bad debt expense. The use of the new percentage resulted in the $1,900 bad debt expense being $500 less than the amount that would have been calculated using the old percentage.

During 2017, the company elected to switch from the completed contract method to the percentage of completion method for the work performed by its Consulting Division. This division has been in existence since 2015. The effect of this change was an increase in revenue in 2015 of $15,000, an increase in 2016 of $20,000 and an increase in 2017 of $25,000. The percentage of completion method was applied to all consulting revenue recorded in 2017. Consulting revenue is combined with other sales revenue for reporting purposes on the financial statements.

Which of the “additional information” items would require footnote disclosure? Briefly explain what the footnote would need to state or explain.

Before you begin this discussion, find a coin and flip it 10 times, recording the outcome of each flip as either heads or tails. Post your results in this discussion, along with the percentage of flips that resulted in heads. We might expect that percentage to be 50%, but the results may vary from student to student (sometimes drastically) in this exercise. As a response to other students, add their data to yours and compute the new percentage of flips that result in heads (You can just make up realistic predictions for the other students). With enough data added, what would you expect to find? What does the central limit theorem have to say about the long-term outcome of exercises like this?

The weight of an organ in adult males has a bell-shaped distribution with a mean of 300 grams and a standard deviation of 45 grams. Use the empirical rule to determine the following.

(a) About 68% of organs will be between what weights?

(b) What percentage of organs weighs between 165 grams and 435 grams?

(c) What percentage of organs weighs less than 165 grams or more than 435 grams?

(d) What percentage of organs weighs between 255 grams and 435 grams?

(A) _ and _grams. (use ascending order.)

(B) _ % (type an integer or a decimal.)

(C) _ % (type an integer or a decimal.)

(D) _% (type an integer or decimal rounded to two decimal places as needed.)

8. The percentage of sales method has been used to forecast the firm’s financial statements. Sup-pose one of the senior executives asked you what assumptions are implied when one uses the percentage of sales method. That is, under what circumstances would the percentage of sales method produce a valid, as opposed to an incorrect, forecast? How would you answer? 9.

9.What are some other methods that could be used to forecast the asset-and-liability balances and, thus, the forecasted financial requirements? If the senior executives asked you to incor-porate these procedures into your analysis, how would you do it, how long would it take, and what additional data would you require

1. Each of the following situations describes error in a statistical experiment, where a researcher is trying to find the percentage of American college students who identify as Democrats or Republicans. State whether this is sampling or non-sampling error, and explain why you chose that answer.
   1. The researcher randomly selects 400 college students from around the country and asks them if they are Democrats or Republicans. The researcher finds that 38% of the students are Democrats, when the actual percentage is 41%.
   2. The researcher sets up a table in the cafeteria at their University, a wealthy private school in New England, and asks students who pass by if they identify as a Democrat or Republican. They find that 53% of the surveyed students identify as Republicans, when the actual percentage is 36%.

The question was:

Finals are over and the marks are in. For all the students who have completed the introductory course to business statistics the distribution of the grades represented a bell-shaped distribution, symmetrical about the average which was 75.90 marks. The standard deviation was 1.40.

Given the information above, answer the following questions using the Empirical Rule.

For full marks your answer should be accurate to at least two decimal places.

a) Approximately what percentage of marks were above 77.30?

b) Approximately what percentage of marks were below 71.70?

c) Approximately what percentage of marks were between 71.70 and 80.10?
