Discuss in detail (not just enumerate) at least three factors that contribute to the current worldwide expansion of vector-transmitted diseases.

Explain in some detail (not just enumerate) at least FOUR factors that contribute to healthcare-associated infections and four strategies to reduce their incidence.

With the use of a phase shift, the position of an object may be modeled as a cosine or sine function (as a function of time). If given the option, which function would you choose (Note: this is an open-ended question; there is no wrong answer; just be sure to explain your choice)? Assuming zero phase shift, if you are using a sine function to model the position of an object, what are the initial conditions of the oscillator---that is, the initial position, velocity, and acceleration of the oscillator at t = 0? How about if you use a cosine function to model the position?

3-1. On your first visit with gray sharma, he tells you he would like to know about some basic network designs. use microsoft paint or another drawing package to draw examples of the basic network topologies for gray. then, use the space below to summarize those topologies.

Explain the advantages and disadvantages of the topologies you summarized for gray in Assignment 3-1. Based on what you know at this point, which topology would you recommend for the physicians building? why would you recommend it?

Spam is of concern to anyone with an e-mail address. Several companies offer protection by eliminating spam e-mails as soon as they hit an inbox. To examine one such product, a manager randomly sampled his daily emails for 50 days after installing spam software. A total of 374 e-mails were received, of which 15 were spam. Is there evidence that the proportion of spam getting through is greater than 2%? α = 0.10 a. State your hypotheses. b. Which hypothesis test should you use? c. State your rejection rule (use the p-value approach). d. Show how the test statistic was calculated (write down the formula and plug in the numbers). e. What is the p-value? f. State your conclusion.

For this problem, you will use the data in the Emission Level column. A major car manufacturer wants to test a new engine to determine whether it meets new air-pollution standards. The mean emission ? of all engines of this type must be less than 20 parts per million (ppm) of carbon. Ten engines are manufactured for testing purposes, and the emission level of each is determined. The data is given in ppm. The test will be run with ? = 0.01. Assume it is known that ? = 3.01. a. State mathematically the null and alternative hypotheses for this test. H0: _________________________ H1: _________________________ b. State the decision rule for the test. c. (1) You might need Minitab to find the descriptive statistics for you, but then find the test statistic and pvalue “by hand,” showing all work/explanations below. (2) Use Minitab to run the appropriate hypothesis test (i.e., choose between the 1-sample Z and the 1-sample t in the Stat | Basic Statistics menu). Your choice for the Hypothesized mean (the nullhypothesized value for the mean) and the sign for Alternative hypothesis (found under Options) should match the hypotheses you wrote in part (a). Paste ALL of the Minitab output into this document, from the test name all the way down to the p-value. At the end of the output, state the test statistic and the p-value. d. State your conclusion to the hypothesis test – include a statement about rejecting or retaining H0 (and why) and also a concluding statement in plain English about emission level. Module 8 – Fishbowl Assignment – Group 1 e. In order to run the above test, we needed to know that the distribution of X is (approximately) normal. How do we know it is? Justify your answer. Listed are the ten engine data 15.6 16.2 22.5 20.5 16.4 19.4 16.6 17.9 12.7 13.9

You have a patient being discharged home with CHF and diabetes. This patient is a frequent flyer so you want to facilitate their transition to home as best as possible. In 300-500 words, identify 1- 2 important technologies you have learned about, read about or used in patient care that could be considered for use at home in order to promote patient safety for this particular patient. Explain what it is, how it is used, how it promotes safety and why it would help maintain the patient’s health and minimize the likelihood of readmission. Give the top reason for your selection and identify one improvement that you feel would enhance your identified technology.

In this laboratory experiment, you wanted to see the effect of Amylase with starch. So you performed the following:

In tube 1 - Combine equal volume of Amylase with Starch solution

In tube 2 - Combine Amylase with water

In tube 3 - Combine water with Starch solution

Let all three tubes sit in a 37C waterbath for 20 minutes. After the 20 minutes incubation was over, then you would test for the presence of starch. In the meantime, what would you predict? Based on what you know about enzymatic digestion, what do you expect here in these tubes? After the incubation period we added Iodine solutions to each tube to test for starch. Here are the results:

In tube 1 - white cloudy solution

In tube 2 - Yellowish solution

In tube 3 - Dark red solution

Explain this result, what happened in each tube? Why is adding iodine important to detect the presence of starch?

Consider a Specific Factors model of a competitive economy in which 2 goods (Manufacturing products and Agricultural products) are each produced with a specific input (capital and land respectively) and labour is an input in the production of both goods.

1. Assume that the economy exports agricultural products. Use a PPF diagram with Agriculture on the vertical axis to illustrate this equilibrium and clearly show how much of each good is produced, consumed and traded.
2. Illustrate the impact on the equilibrium of an increase in the relative price of manufacturing goods that does not eliminate the economy’s comparative advantage in agricultural goods . Again, show amounts produced, consumed and traded.
3. Will this increase raise or lower the return to land? Explain your answer in detail.
