1. “Type I Error Blues,” by David Stein

The managers huddled to see if they had won or lost.

Did the new process from 2 months before yield data showing a reduction in cost?

Or was it merely a matter of chance…

Too soon to do the data dance?

So they set about the business of crafting a hypothesis test

In order to conclude which process was best.

With the null hypothesis meaning “status quo”, no change evident

They quickly concluded H₀ could not stand, as was their true intent.

Just one month later, they realized their grave mistake!

A Type II error would have been so much safer, for goodness sake.

Alas, their final huddle was a sad one with HR Director Bob.

He told them to go back to training school as each was now in need of a new job.

1. What was the likely managerial mood and outcome on the days immediately following the (erroneous) conclusion to reject this null hypothesis?

2. What would have been the likely managerial mood and outcome on the days immediately following an (erroneous) conclusion not to reject the null hypothesis?

3. In the presence of a Type II Error, what do you suppose would have happened to their cost reduction/process improvement efforts 3-6 months down the road? Please explain in everyday English.

I was stuck on the following review problem on hypothesis testing. Could you please guide me on how to approach this type of problem?

Stacy, a professional soccer player, had a field goal percentage (i.e., probability of making a shot) of p₀ = 60% before needing to take a season off to recover from an injury.

(a) Since returning to the game from injury, Stacy has made 13 out of n = 20 shots. Is Stacy's new, post-injury field goal percentage higher than her old percentage p₀? Perform a suitable one-sided hypothesis test and state your conclusion, taking α = 0.05.

(b) Suppose that the true new field goal percentage is p, where p ∈ (0.6, 1). If we perform a one-sided test as above and want to achieve a type-I error rate of 0.05 and type-II error rate of 0.025, what is the number of shots n needed since returning from injury? Provide an approximate formula as a function of p, and compute the values of n for each of p = 0.8, 0.7, 0.61 (Notice that if p is very close to 0.6 then you may need a very large number of shots.)

(c) Stacy scored X points in a high school game. Knowing that X is greater than 100, find X.

Payback Period and NPV of a Cost Reduction Proposal—Differential Analysis
Katy Zimmerman decided to purchase a new automobile. Being concerned about environmental issues, she is leaning toward the hybrid rather than the completely gasoline four-cylinder model. Nevertheless, as a new business school graduate, she wants to determine if there is an economic justification for purchasing the hybrid, which costs $1,200 more than the regular VUE. She has determined that city/highway combined gas mileage of the Green VUE and regular VUE models are 27 and 23 miles per gallon respectively. Mary anticipates she will travel an average of 12,000 miles per year for the next several years. (Round your answers to two decimal places.)

Determine the payback period of the incremental investment if gasoline costs $3.50 per gallon.

Answer (in years)

Assuming that Mary plans to keep the car five years and does not believe there will be a trade-in premium associated withthe hybrid model, determine the net present value of the incremental investment at an eight percent time value of money. (Use a negative sign with your answer.)

Answer (in dollars)

Determine the cost of gasoline required for a payback period of three years.

Answers (4 in gallon)

At $3.50 per gallon, determine the VUE Green combined gas mileage required for a payback period of three years.

Answer (miles per gallon)

In an article titled "Learning To Keep Learning" in the New York Times, dated December 13, 2006, Thomas L. Friedman states:

"I listened to this with mixed emotions. Part of me said 'Gosh, wouldn't it be nice to have a government that was so focused on innovation -- instead of one that is basically anti-science.' My other emotion was skepticism. Oh, you know the line: Great Britain dominated the 19th century, America dominated the 20th and now China is going to dominate the 21st. It's game over.

"No question, China has been able to command an impressive effort to end illiteracy, greatly increasing its number of high school grads and new universities. But I still believe it is very hard to produce a culture of innovation in a country that censors [Google] which for me is a proxy for curtailing people's ability to imagine and try anything they want. You can command K-12 education. But you can't command innovation. Rigor and competence, without freedom, will take China only so far. China will have to find a way to loosen up, without losing control, if it wants to be a truly innovative nation."

“Hello, I am Lillian Tudor, and I was married to my high school sweetheart, Earl, for 53 wonderful years. He died 2 years ago and I miss him to this day. Earl and I had three children, two of whom passed before Earl. Our oldest daughter, Leigh, is still helping me around the house and is a blessing to me in my old age. Let me tell you something. Getting old ain’t for sissies! I’m 84 years old as of last month. Leigh had the family meet at a buffet restaurant in town for a surprise party! It was nice to see the grandkids, because they don’t stop by often enough with their busy lives. Lynn, the oldest, has a great husband and two kids with more energy than what seems humanly possible. Leigh complains that they are too loud, but I think everyone else talks too softly these days! In fact, when Leigh comes over to take me to the doctor, she’s always telling me my television is too loud.  

“I have a lot of doctors who I see. There’s one for my heart and blood pressure who says my cholesterol is too high and wants me to start a new medicine. Another one is for the diabetes, which makes me use those stupid syringes to take insulin. And the last one is for trying to help me with my stiff knees and sore joints. Like I said, getting old ain’tfor a sissy! Did I mention the adult briefs I wear to help with my bladder leakage? It’s those dang water pills that I take to keep my feet from swelling so badly. All in all, it’s not a bad life.”

In addition to what Lillian has told you, here is a list of her current medications.

Captopril 25 mg, three times a day   

Alprazolam (Xanax) 0.5 mg, by mouth as needed for anxiety  

Insulin lispro (Humalog) 7 units subcutaneous TID, 15 minutes before meals   

Tramadol for arthritis pain  

Furosemide 40 mg, twice per day   

Ciprofloxacin 250 mg every 12 hours  

Pilocarpine eye drops, two drops each eye, four times a day   

Lasix 60 mg, once per day in the morning  

Select one medication and answer all five of the following questions.

1. If this was a medication order, do you have enough information to safely administer the medication? Please explain your answer and provide the missing information, if any.

2. What is the medication’s classification? Does it have any special considerations about which the nurse should be aware?

3. Why is Lillian taking this medication? If you are unsure based on the information you’ve been given thus far, list common reasons for this medication to be given.

4. Does this medication present any possible adverse interactions with the other medications Lillian is taking?

5. What are the implications of Lillian taking garlic supplements with her current Drug Interactions?“Hello, I am Lillian Tudor, and I was married to my high school sweetheart, Earl, for 53 wonderful years.
