You are a medical student on placement at Freeman Hospital. You are on placement with another first year student from the same university called James. James is working the same shifts as you.

You have been working the same morning shift as James for the last three (3) days. At morning tea James tells you that he hates his placement, is learning nothing and has complained on the student Twitter page.

You check the Twitter page and see the following post from James:

Warning! All nursing students

On WPL at Freeman Hospital. The medical ward is disgraceful – doing nothing but making beds and wiping old peoples’ backsides. To top it all off, for all those Melbourne students, am working with “you know who” – L.S is unsafe and wonders around all day looking stupid.

Looked after John aged 89 yesterday and had to change his bed 3 times. His daughter gave me $50 at the end of shift – bonus!!

You are horrified to see what James has written about the ward, the patients and also as your initials feature in the post as the “unsafe” fellow student. You reflect on James's behaviour in light of the Code of conduct and Code of ethics……

Question 1 (800 words maximum)

James's behaviour does not reflect the Nursing and Midwifery Board of Australia’s (NMBA) Code of conduct for nurses (2018). How is James's behaviour in breach of the NMBA Code of conduct for nurses (2018) ?

Question 2 (400 words maximum)

James's behaviour is also not reflective of the International Council of Nurses (ICN) Code of ethics for nurses (2012). How is James's behaviour in breach of the ICN Code of ethics for nurses (2012)?

Some years ago a small university did an SRS survey of students that graduated 20 years previously to find out their current income. From that data it found the income graduates had 20 years after they graduated varied between degrees. Because the number of students graduating 20 years ago varies by degree it was decided a stratified sample should be done this year to improve the precision of the analysis. The five degrees are listed below with the number of students who graduated in 1999 along with the estimated variance of the responses for each strata based on the last survey’s responses.

This year the investigators can afford to survey 40 graduates from 1999.

1. Calculate the sample size for each strata and sample error at 95% confidence level if the number sampled for each strata is the same.
2. Use proportional allocation to calculate the number to be sampled in each strata. Calculate the sample error at the 95% confidence level.
3. Using Neyman allocation (the cost to sample a unit in any strata is the same) to calculate the number to be sampled in each strata. Calculate the sample error at the 95% confidence level.
4. Explain why the results for the sample error in a), b) and c) are different.
5. Normally the variance of the variable y we are measuring is not known so we cannot stratify using it. Instead we often use the variance for an auxiliary variable which is known for all units. If there were several possible auxiliary variables available explain how you would choose which one to use.

Please answer all questions

1. A pro basketball player is a poor​ free-throw shooter. Consider situations in which he shoots a pair of free throws. The probability that he makes the first free throw is 0.51. Given that he makes the​ first, suppose the probability that he makes the second is 0.64. Given that he misses the​ first, suppose the probability that he makes the second one is 0.36.

What is the Probability he makes both free throws?

2. The most likely scenario for an accident for a natural gas pipeline is​ natural-gas leakage from a hole in the pipeline. The probability that the leak ignites immediately​ (I) causing a jet fire is .03. If the leak does not immediately​ ignite, it may result in the delayed ignition​ (D) of a gas cloud. If there is no delayed​ ignition, the gas cloud will disperse harmlessly​ (H). Given no immediate​ ignition, the probability of delayed ignition causing a flash fire is .03. Suppose a leak occurs in the​ natural-gas pipeline.

The probability that either a jet fire or a flash fire will occur is?

3. Red snapper is a rare and expensive reef fish served at upscale restaurants. A certain law prohibits restaurants from serving a​ cheaper, look-alike variety of fish​ (vermilion snapper or lane​ snapper) to customers who order red snapper. Researchers at a university used DNA analysis to examine fish specimens labeled​ "red snapper" that were purchased form vendors across the country. The DNA tests revealed that 78​% of the specimens were not red​ snapper, but the​ cheaper, look-alike variety of fish.

Assuming that the results of the DNA analysis are​ valid, what is the probability that you are actually served red snapper the next time you order it at a​ restaurant?

The probability is?

Prior research has shown a significant relationship between maternal smoking during pregnancy. Investigators at University Anywhere were interested in looking at whether or not there was a dose response between smoking and low birth weight. They collected data from 500 women receiving prenatal care at a local health center and categorized their smoking status at their first prenatal visit into the following categories:

(1) never smokers, (2) former smoker (quit smoking) (3) non-daily smoker (currently smokes but not every day) and (4) daily smoker. The table below provides a descriptive summary of data from the study:

A. Describe what type of graph you would use to examine the relationship between maternal smoking and birth weight. Justify the graph you selected.

B. What statistical test can be performed to see if the mean birth weight varied across the smoking categories? Be sure to include a brief explanation/justification for the test that you selected.

C. Specify the null and alternative hypotheses for the test that you specify in part b.

D. Perform the test you suggested in part b, report a p-value

E. Interpret this result in a sentence (remember that your interpretation should be one that makes sense to the scientific community who will use these results, not just biostatisticians).

F. What else would you like to know in order to address this hypothesis? Describe how you would examine this.

Question: What is the recognized gain (loss) on sale of equipment if Horizon Insurance elects to outsource publishing to G-Art? please use a dash "-" for a loss on sale.

Use the following case to help answer this question:

Horizon Insurance (HI) was a full-service regional insurance agency that has done all the printing and publishing of its own promotional brochures, newsletters, informational pamphlets, and required regulatory reports. Linda Wolfe, the business manager of the agency, had for some time thought that the firm might save money and get equally good services by contracting the publishing work G-Art Inc. She asked G-Art Inc. to give her a quote at the same time she asked Bob Myer her controller to prepare an up-to-date statement of the cost of operating Horizon’s publishing department.

Within a few days, the quote from G-Art Inc. arrived. The firm was prepared to provide all the required publications work for $ 410,000 a year with the contract running a guaranteed term of 4 years with annual renewals thereafter. If the estimated number or assumed mix of publications changed in any given year beyond the baseline planning estimates, the contract price would be adjusted accordingly. Wolfe compared G-Art’s quote with the internal cost figures prepared by Myer:

Table 1; Annual cost of operating HI’s publications department: Myer’s figures.

Materials                                                                                                             $40,000

Labor                                                                                                                 $290,000

Department overhead

Manager’s salary $48,000                                  

Allocated cost of office space                                  $10,000

Depreciation of equipment                                       $32,500

Other expenses (travel, education, ect.) $25,000

                                                                                                                             $115,500

                                                                                                                            $445,500

Share of company administrative overhead $30,000

Total cost of department for year $475,000

Wolfe’s initial conclusion was to close Horizon’s publications department and immediately sign the contact offered by G-Art. However, she felt it prudent to give the manager of the department, George Richards, an opportunity to question that tentative conclusion. She called him in and put the facts before him, while at the same time making it clear that Richards’ own job at the agency was not in jeopardy.

Richard came up with the following to keep in mind before his department was closed:

For instance, what will you do with the customed graphic design and printing equipment? It cost $260,000 four years ago, but you’d be lucky if you got $80,000 for it now, even though we had planned on using it for another four years at least. Andthen there is the sizable supply of print materials that includes a lot of specialized ink, specialty card stock, paper, envelopes ect. We bought the custom supplies a year ago when we were pretty flush with cash. At that time it cost us about 125,000 and at the rate we are using it now, it will last us another four years. We used up about one-fifth of it last year. As best as I an tell, Myer’s figure of $40,000 for materials includes about $25,000 for these customized sipplies and $15,000 for generic supplies we use on a regular basis. If we were to buy these custom supplies today it would probably cost us 110% of what we paid for it. But if we try to sell it, we would probably get only 60% of what we paid for it.

Wolf thought that Myer ought to be present during this discussion. She called him in and put Richard’s points to him. Myer said:

If we are going to have all of this talk about “what will happen if” don’t forget the problem of space we’re faced with. We’re paying 12,000 a year in outside office space. If we close Richard’s department we could use of the freed-up space as office space and not need to rent it on the outside.

Wolfe replied:

That’s a good point, though I must say I’m a bit worried about the people if we close the publications department. I don’t think we can find room for any of them elsewhere in the firm. I could see whether G-rt can take any of them, but some of them are getting odler. There’s Walters and Hines, for example. They’ve been with us since they left school 40 years ago, and I think their contract requires us to give them a total severance payoff of about $60,000 each, payable in equal amounts over four years.

Richards showed some relief at this. “ But I still don’t like Myer’s figures” he said. “What about the $30,000 for general administrative overhead. You surely don’t expect to fire anyone in the corporate office if Im closed, do you?

“Probably not” said Myer, but someone has to pay for those costs. We can’t ignore them when we look at an individual department, because fi we do that with each department in turn, we will convince ourselves that accountants, laywers, vice presidents, and the like don’t’ have to be paid for. And they do, believe me”

Clarification: In the fact set, Custom Supplies are expected to sell for 60% of what the company paid for them. Assume (to make numbers cleaner), that this is 60% of their 'current' book value of $100,000 (derived from the fact set), not the original cost.

Some experts agree that who we are is a result of Nurture—the social relationships or the influence of Socialization. Others argue that who we are is based on genetics. According to this belief, our basic temperaments and interests are set before birth. From this perspective, then, who we are depends on the mighty Nature.

Primary spermatocytes are diploid (2n) cells with all of the organelles typically found in eukaryotic animal cells. A representation of spermatogenesis from a primary spermatocyte with six chromosomes is shown in Figure 1.

(a)  Describe the process in meiosis that ensures that both maternal and paternal chromosomes are passed on to each spermatozoon.

Question 2

(b)  Explain why the genetic content of individual chromosomes in a spermatozoon most likely differs from the genetic content of individual chromosomes in a primary spermatocyte.

Question 3

(c) In some instances, meiosis of a primary spermatocyte with six chromosomes results in two spermatozoa that contain four chromosomes and two spermatozoa that contain two chromosomes.  Predict the most likely cause.

Question 4

(d) A student claims that if the animal producing the spermatozoa has a mutation in a mitochondrial gene, the probability that any offspring will inherit the mutation is zero. Provide evidence to support this claim.
