In a study of red/green color blindness, 900 men and 3000 women are randomly selected and tested. Among the men, 84 have red/green color blindness. Among the women, 6 have red/green color blindness. Test the claim that men have a higher rate of red/green color blindness.
(Note: Type ?_? ???=?_? for the proportions are not equal, ?_?>?_? for the proportion of men with color blindness is larger, ?_?<?_? , for the proportion of men is smaller, and ?_?=?_? for the proportions are equal. )

(a) State the null hypothesis:

(b) State the alternative hypothesis:

(c) The test statistic is  (to two decimal places)

(d) Construct the 99% confidence interval for the difference between the color blindness rates of men and women (round to at least three decimal places). Remember to recalculate the SE, since it is different for CIs and tests.

One factor in rating a National Hockey League team is the mean weight of its players....

One factor in rating a National Hockey League team is the mean weight of its players. A random sample of players from the Detroit Red Wings was obtained. The weight (in pounds) of each player was carefully measured, and the resulting data have a sample size of 18 with a sample mean of 208 pounds and a sample standard deviation of 11.1 pounds. You can assume that all of the assumptions are met.

a) What are the assumptions that are required to perform inference on this data?

b) Should you use a z distribution or a t distribution in this problem. Note that you will only get one try to get this question correct.

c) Please explain the correct answer.

d) Find the 95.9% confidence interval for the true mean weight of the players from the Detroit Red Wings.

i) If this would be a z distribution, what would be the critical value? Please use 4 decimal places.

ii) If this would be a t distribution, what would be the critical value? Please use 4 decimal places.

iii) If this would be a t distribution, what would be the degrees of freedom?

iv) The 95.9% confidence interval for the true mean weight of the players from the Detroit Red Wings is

e) Interpret your answer from the interval above (part d)

f) Please show all of the code for this part (part d) below

g) If the half-width of the interval needed to be at most 5.23 pounds, how many players would have to be randomly sampled from the team? Please use at least 4 decimal places in all numbers used (unless the number is exact). Note: This number might not be realistic. What is the new sample size?

h) Please show all of the code for this part (part g) below

Using South University Online Library or the Internet, research on a sexually transmitted disease (STD) policy of the state you reside in. Once you identify an STD policy from the state you reside in, visit your state health department or browse your state's website and search for the STD policy you selected.

Next, write a research paper describing this public health policy analysis and background. The final paper should include the following:

A title page

An introduction of policy analysis in two to three paragraphs discussing the following:

Overview

Purpose

A bodyHealth policy background (one page):

The state's role in the policy-making process

The purpose of public health policy

Public health policy analysis five-step process discussing the following:

A problem statement (in the form of a question) (two paragraphs)

Background of a policy analysis provides factual information needed to understand the problem. Include economic issues of policy as well as regulatory policy (two pages).

The landscape section of a policy analysis identifies key stakeholders and describes the factors that are needed to analyze the problem. Write the landscape section on policy analysis. Include balance of patient rights versus protecting the population. Include any influence from government insurance programs. Your response should be of at least three pages

Options (three or four) to address the policy problem. Your response should be of at least three pages.

Recommendations section should clearly identify three options. Which of the three options is favored and why is it is preferred over the other ones. Your response should be of at least one page.

A conclusionYour conclusion (one page) should address the following main points:

Your recommendation and the reasoning behind it.

Summarize your findings.

Explain the barriers to implementing policy analysis process and how they could be overcome.

Your paper should be a minimum of 12- to 13-pages in a Microsoft Word document. You need a minimum of six scholarly sources for both in-text citations and citations on the reference page.

In 2000, the percentage of adults in a certain town who drove an SUV was 53%. In 2005, in a random sample of 100 people from this town, 45 said that they drive an SUV. At the 10% level of significance, use the critical-value method to determine if the percentage of adults in this town who drive an SUV has changed from the 2000 percentage. Correctly state a) your conclusion about what to do with H0 AND b) your conclusion about the claim that is being made.

A charge neutral macrocyclic ligand having four donor atoms froms a red, diamagnetic complex of Ni(II). The counter ions for this complex is the very weak Lewis base, ClO4-. When ClO4- is replaced by thiocyanate, violet complex forms.

a. Draw the structures of the red and violet complexes such that thier geometires can be decerned based only on your drawings.

b. Draw the d-orbital slitting diagrams of the red and violet complexes such that the relative energies of the orbitals in the two complexes can be compared.

c. Wse your orbital diagrams to show were the d electroms reside in each complex. Explain your electron configurations.

d. describe an experiment that you could do to test whether your predicted electron configurations are reasonable. Show what the results of this experiment would be for the d electron configureation that you showed in part c

This paper is grounded in the text Criminology: A Canadian Perspective. This paper contains two parts:
First, students should answer the question: “What is criminology?” The answer to this question should be a descriptive overview of what you have gleaned from the text.
Second, students should provide a reflection on the first section of the paper. A reflection is another way of saying “What do you think about what you have studied and written?”.
Some ideas for reflection questions might be: What did you learn? Does what you have learned make you uncomfortable? Why? Is criminology what you thought it would be when you entered this course?
These are your thoughts. Accordingly, this section is about your thoughts so should contain your thoughts only. This paper is not about what Google, a book review or some random article on the internet thinks. You are strongly discouraged from even looking towards outside sources of any kind, and no outside sources should be used beyond the primary text. In fact, using outside sources will result in a penalty.
