Imagine that you have decided to open a small ice cream stand on
campus called "Ice-Campusades." You are very excited because you
love ice cream (delicious!) and this is a fun way for you to apply
your business and economics skills! Here is the first month's
scenario--you order the same number (and the same variety) of ice
creams each day from the ice cream suppliers, and your ice creams
are always marked at $1.50 each. However, you notice that there are
days when ice creams remain unsold but other days when there are
not enough ice creams for the number of customers.
Use your knowledge of the factors that cause shifts in demand, and
in a multi-paragraph essay, provide at least three reasons why ice
cream sales fluctuate in this manner. (Apply only the factors you
think are applicable to explaining this scenario.) Now assume that
a month later, the school allows a competing student the right to
sell ice creams on school property. (The number of students on
campus remains largely unchanged.) What do you think will happen to
the price of ice cream at your campus? Explain in detail.
Develop a response that includes examples and evidence to support
your ideas, and which clearly communicates the required message to
your audience. Organize your response in a clear and logical manner
as appropriate for the genre of writing. Use well-structured
sentences, audience-appropriate language, and correct conventions
of standard American English.

You are part of a team that is evaluating the feasibility of building a standardized nursing language into the electronic medical record that will be used by your department. Your group is reviewing the 12 ANA recognized terminologies. The goal is to make recommendations about one or more terminologies that could be built into EMR for use by nurses. Choose one of the 12 ANA recognized terminologies to evaluate (read materials for this unit and visit the website of the sponsoring organization) and answer the following questions:
Which ANA recognized terminology did you evaluate?
What additional information about the terminology did you learn when you visited the sponsoring organization's website?
What would your recommendations be about implementation of the terminology you evaluated into the EMR?
If you did use this standardized terminology in nursing, what would you need to do to prepare staff to think about nursing care and document differently?

A local bank claims that the waiting time for its customers to be served is the lowest in the area. A competitor bank checks the waiting times at both banks. The sample statistics are listed below. Test the local bank's claim. Use the information given below. Use the significant level of .05 and assume the variances are equal.
| sample size |
Local Bank n1 = 46 |
Competitor Bank n2 = 50 |
| Average waiting time in minutes for each sample | Xbar1 = 2.3 mins | Xbar2 = 2.6 mins |
| Sample Standard Deviation of each Sample | S1 = 1.1 mins | S2 = 1.0 mins |
1. Are the samples dependent or independent?
2. State your Null/Alternative hypotheses
3. What is the test-statistic?
4. What is the p-value?
5. What are the critical values?
6. Does the test-statistic lie in the rejection region?
7. Interpret the result?
8. Does the result change for a different value of alpha? Explain?

Arteriosclerotic plaques forming on the inner walls of arteries can decrease the effective cross-sectional area of an artery. Even small changes in the effective area of an artery can lead to very large changes in the blood pressure in the artery and possibly to the collapse of the blood vessel.
Imagine a healthy artery, with blood flow velocity of v0=0.14m/s and mass per unit volume of ρ=1050kg/m3. The kinetic energy per unit volume of blood is given by K0=12ρv20.
Imagine that plaque has narrowed an artery to one-fifth of its normal cross-sectional area (an 80% blockage).
A) Compared to normal blood flow velocity, v0, what is the velocity of blood as it passes through this blockage? (Show your work)
B) By what factor does the kinetic energy per unit of blood volume change as the blood passes through this blockage?
C) As the blood passes through this blockage, what happens to the blood pressure?
1. It increases by about 41 Pa
2. It increases by about 250 Pa
3. It stays the same
4. It decreases by about 41 Pa
5. It decreases by about 250 Pa
D) Relative to its initial, healthy state, by what factor does the velocity of blood increase as the blood passes through this blockage?
E) By what factor does the kinetic energy per unit of blood volume increase as the blood passes through this blockage?
F) What is the magnitude of the drop in blood pressure, Δp, as the blood passes through this blockage? Use K0 as the normal (i.e., unblocked) kinetic energy per unit volume of the blood. (Show your work)

Density is a physical property which plays a very
important role in our daily life. It is very widely used in all
field of engineering. Density is widely used for choosing the
suitability of a material for a specific purpose.
a) Discuss how density is finding its application in
Marine engineering field in not more than 100 to 150 words.
b) Describe the way in which you can determine the density of given
substances. Also explain the tools which are used for finding the
density. Explain in detail.
c) You are given a cylindrical shaped silver having diameter X cm
and height Y cm.
[ You can take X – the first two digits of your student ID and Y –
the last two digits of your student ID. For e.g., If the student’s
ID is 1875-18, The X = 18 and Y = 75]. The density of silver is
10.5 g/cm3. Calculate the mass of the silver shape given to you in
kg/m3.
[ for conversion you can use - 1 m = 100 cm and 1 kg = 1000 g]

A researcher at the Annenberg School of Communication is interested in studying the use of smartphones among young adults. She wants to know the average amount of time that college students in the United States hold a smartphone in their hand each day. The researcher obtains data for one day from a random sample of 25 college students (who own smartphones). She installs an app that registers whenever the smartphone is being held and the screen is on. The sample mean is 230 minutes, with a standard deviation of 11 minutes.
What is the 99% confidence interval for average daily time a smartphone is used among college students?
What is the lower bound of the confidence interval?
What is the upper bound of the confidence interval?
What decision should the researcher make about the null hypothesis? Be sure to explain your answer (e.g., what numbers provide the basis for this decision?).
Would our decision about the null hypothesis have been different if the researcher had initially hypothesized that women spend more time talking on their phones than men?
Explain all parts/information necessary to answer this question.
