1. Explain what it means for the normal distribution to be symmetrical about the mean?

2. Why is it important to know the mean and standard deviation for a data set when applying the empirical rule?

3. If we are focused on 68% of the normal distribution, what percentage of the distribution is left in the upper tail only?

4. What value separates the 50% of the distribution from the other 50% of the distribution?

1.   Discuss Central Line-Associated Bloodstream Infection (CLABI)
"or" Ventilator-Associated Pneumonia (VAP) outbreak in long-term acute care hospital
settings. Address the following in your report:
a)   Characterize the epidemiology and microbiology
b)   Describe the agent, and identify the host and the environment that is favorable
for the infection.
c)   Discuss how the infections spread and the types of prevention and
control measures
d)   Identify a population and develop a hypothesis about possible causes
in a testable format with standard statistical notation (the null and the alternative)
e)   Explain how you would choose controls to test this hypothesis?

The belief is that the mean number of hours per week of part-time work of high school seniors in a city is 10.4 hours. Data from a simple random sample of 21 high school seniors indicated that their mean number of part-time work was 11.4 with a standard deviation of 1.2. Test whether these data cast doubt on the current belief. (use α = 0.05)

Part a: State your null and alternative hypotheses.

Part b: State the rejection region.

Part c: Calculate the test statistic.

Part d: Determine the P-value for your test.

Part e: State your conclusion for your hypothesis test.

Interview a certified special education teacher at the educational level (PK- 12) of your program, about the following:

What are some similarities and differences among students with and without exceptionalities?
What are some characteristics of various exceptionalities and the educational implications for students with exceptionalities?
What is the effect an exceptionality can have on a student's academic and social development, attitudes, interests, and values?
How do you collaborate with general education teachers?
In what ways do you address the unique learning needs of the individuals with exceptionalities in the classroom, including for those students with culturally and linguistically diverse backgrounds?
How do you protect the privacy of students with exceptionalities? What are some dilemmas you have experienced with this?

In 250-500 words, summarize and reflect upon your interview and on the professionalism and integrity of protecting student privacy. In addition, be sure to explain how you will use your findings in your future professional practice, citing two recommended strategies for differentiating instruction based on learning differences.

You have been asked by the president of your company to evaluate the proposed acquisition of a new special-purpose truck for $70,000. The truck falls into the MACRS 3-year class, is not eligible for either bonus depreciation or Section 179 expensing, and it will be sold after three years for $20,200. Use of the truck will require an increase in NWC (spare parts inventory) of $2,200. The truck will have no effect on revenues, but it is expected to save the firm $23,500 per year in before-tax operating costs, mainly labor. The firm’s marginal tax rate is 21 percent. What will the cash flows for this project be? (Negative amounts should be indicated by a minus sign. Round your answers to 2 decimal places.)

You have been asked by the president of your company to evaluate the proposed acquisition of a new special-purpose truck for $50,000. The truck falls into the MACRS 3-year class, is not eligible for either bonus depreciation or Section 179 expensing, and it will be sold after three years for $20,100. Use of the truck will require an increase in NWC (spare parts inventory) of $2,100. The truck will have no effect on revenues, but it is expected to save the firm $17,000 per year in before-tax operating costs, mainly labor. The firm’s marginal tax rate is 21 percent. What will the cash flows for this project be? (Negative amounts should be indicated by a minus sign. Round your answers to 2 decimal places.)

Suppose the incidence of ketosis in Holstein dairy cows is 11.8% in the state of Michigan (Dyk and Emery, 1996; Proc Tri-State Nutrition Conference). Assume the state of ketosis (1 = diseased, 0 = not-diseased) is independent between all animals; i.e., the occurrence or non-occurence of ketosis on any one animal is in no way related to whether ketosis occurs in any other animal. Furthermore, suppose that there are a large number of herds in the state for which the probability of ketosis (11.8%) was the same for each herd.

A)Within any one herd of size 60, what is the exact probability of having 4 or less cows being afflicted with ketosis.

B)Redo (a) but use a normal approximation to determine this probability. Do this with and without the continuity adjustment. Are either of these results consistent with the exact probability you provided in your answer to a)?

A small helium-neon laser emits red visible light with a power of 5.30 mW in a beam that has a diameter of 2.30 mm .

A)

What is the amplitude of the electric field of the light?

Express your answer with the appropriate units.

B)

What is the amplitude of the magnetic field of the light?

C)

What is the average energy density associated with the electric field?

Express your answer with the appropriate units.

D)

What is the average energy density associated with the magnetic field?

Express your answer with the appropriate units.

E)

What is the total energy contained in a 1.00-m length of the beam?

Express your answer with the appropriate units.
