Water is an essential element of life on earth. A human being can survive for only about one week without water. As the global population expands and increasing industrialization creates ever-growing demands for water, supply of this vital commodity has become endangered. Just as water, clean air is an essential element for the survival of life on earth. Air that is polluted can endanger our health and cause damage to trees, wildlife, and property.

Using the Internet, research on the topic, "Various Health Hazards Caused by Water and Air Pollution.

"Based on your understanding, create a 3- to 4-page Microsoft Word document that includes the answers to the following questions:

What are the hazardous substances that may be found in drinking water and what are their impacts on our health?

Describe how water is made safe for human consumption.

Epidemiologic analyses have demonstrated a correlation between an increase in total daily mortality and an increase in air pollution. Provide examples to explain how historically significant fatal air pollution episodes (that were characterized by extreme increases in air pollution) lead to increase in mortality.

Describe how greenhouse gases contribute to the greenhouse effect.

Explain the term "global warming" and present arguments in favor of and against the proposition that global warming has occurred during the past century. What environmental outcomes have been attributed to global warming?

Care super insurance company has 150 computers that are networked together. It also has four servers and uses a star topology wired network to reach employees' offices, with a bus interconnecting four floors in its office building. Because of a staggering influx of Internet business, the network administrator's task is to boost network performance and availability as much as possible. The company also wants a network design that's easy to reconfigure and change because workgroups form and disband frequently and their membership changes regularly. All computers must share sensitive data and control access to customer files and databases. Aside from customer information and billing databases, which run on all servers, employees' desktop computers must run standard word-processing and spreadsheet programs. Use the following write-on lines to evaluate the requirements for this network. After you finish, determine the best network topology or topology combination for the company. On a blank piece of paper, sketch the network design you think best suits company needs. Remember: High performance and easy reconfiguration are your primary design goals! a. Design a Network topology for the given scenario. b. Will the network be peer-to-peer or server based? Justify your answer. c. Analyse business goals for this network. d. Analyse business priorities for this network. e. Investigate business constraints for this network.

The Federal Reserve System is the central bank of the United States. It performs five general
functions to promote the effective operation of the U.S. economy and, more generally, the public
interest. The Federal Reserve
• conducts the nation’s monetary policy to promote maximum employment, stable prices, and
moderate long-term interest rates in the U.S. economy;
• promotes the stability of the financial system and seeks to minimize and contain systemic
risks through active monitoring and engagement in the U.S. and abroad.
Similarly our central bank BOZ is the equivalent of the FED. The Bank of Zambia (BoZ) is the
Central Bank of the Republic of Zambia and derives its functions and powers from the Bank of
Zambia Act, no,43 of 1996 and the Banking and Financial Services Act, Chapter 387 of the Laws of
Zambia. The Mission Statement of the Bank is to achieve and maintain price and financial system
stability to foster sustainable economic development.
As you can see both appear to be on the same track, critically assess the two banks by carrying out
an in-depth evaluation of their functions and highlight areas of improvement thats could be
recommended to both.

3. According to the Center for Disease Control, 15.2% of adult Americans experience migraine headaches. Stress is a major contributor to the frequency and intensity of headaches. A massage therapist believes that she has a technique that can reduce the frequency and intensity of migraine headaches. The following hypotheses are used to test the effectiveness of the massage therapist’s claim.

Ho: The true proportion of adults who experience migraine headaches after massage therapy is 0.152.

HA: The true proportion of adults who experience migraine headaches after massage therapy is less than 0.152 A.

Describe Type 1 error in the context of this situation. (4 points)

We conclude that proportion of adults who experience migraines after therapy is less than 0.152 when it is not less than 0.152. (We think the therapy is helping but it really is not).

1 pt correct conclusion – “concludes proportion has decreased” 1 pt correct truth – “proportion has not decreased” 2 pts – context for both conclusion and truth Deductions: deduct 1 point if the word proportion is not used

From my understanding a type 1 error is when p > ? and we fail to reject the null hypothesis. Following this mindest Ho cannot be reject. So why is the answer less than 0.152 when it is not less than 0.152? I thought it would be the proportion equals .152 cannot be rejected.

The Lawnpoke Golf Association (LGA) has established rules that manufacturers of golf equipment must meet for their products to be acceptable for LGA events. BatOutaHell Balls uses a proprietary process to produce balls with a mean distances of 295 yards. BatOutaHell is considered that if the mean distance falls below 295 yards, the word will get out and sales will sag. Further, if the mean distance exceeds 295 yards, their balls may be rejected by LGA. Measurements of the distances are recorded in DATA. At a = 0.05, test the no action hypothesis that the balls have a mean distance of 295 yards.

DATA

Please choose one of the following options:

A) Test statistic is 1.297 and the critical value is 1.734, therefore the test statistics is less than the critical value and the null hypothesis is not rejected. The distance is about 295 yards.

B) The test statistic of 1.908 is greater than the critical value of 1.734, therefore H0 is rejected. It is reasonable to assume that the distance is not 295 yards.

C) The test statistic is 3.003 and the critical value is 1.734, therefore the test statistic is greater than the critical value of 1.734 and the null hypothesis is rejected. The distance is not 295 yards.

D) The test statistic of 2.238 is greater than the critical value of 1.734, therefore H) is rejected. It is reasonable to assume that the distance is not 295 yards.

Remember: if p < .05, then you reject the null hypothesis and accept the alternative hypothesis. If p > .05, then you accept the null hypothesis and reject the alternative hypothesis. In a two-tailed hypothesis test, the null hypothesis means there is no significant difference between the groups, then in the alternative hypothesis you state there is a significant difference between the groups. 1. Watch the below video on the Chi-Square Method. Video: Chi-Square Test A. Identify what the null and alternative hypothesis are in the chi-square method video example (use a two-tailed hypothesis for both null and alternative). B. Identify the P value in the video example C. Use hypothesis testing to either accept or reject the null or alternative hypothesis. D. Interpret the results from the video and how they can be applied in real life. 2. Watch the video below on the ANOVA method. Video: ANOVA Excel A. Identify what the null and alternative hypothesis are in the ANOVA method video example (use a two-tailed hypothesis for both null and alternative). B. Identify the P value in the video example C.

How can you use the Chi-Square and ANOVA statistical methods in your future career (200 word minimum).

Currently Sam and Carla have the only taxi services in a small town. Both Sam and Carla are thinking about discounting their respective fares by 20% to attract more business.  

The possible outcomes of this game are as follows.

First: Sam offers discounts, while Carla does not, which will result in Sam earning $400 in profit and Carla earning $800 in profit.

Second: Sam and Carla both offer discounts, which will result in Sam earning $200 in profit and Carla earning $500 in profit.

Third: Sam and Carla both do not offer discounts, which will result in Sam earning $100 in profit and Carla earning $1,000 in profit.

Fourth: Carla offers discounts, while Sam does not, which will result in Sam earning $60 in profit and Carla earning $700 in profit.

An industrial psychologist was interested in the impact of Introductory Message (general greeting, inquiry, or statement) and Type of Phone (land line or cell) on the length of a phone call. The data appear below.

Use SPSS to analyze the data and answer the following questions. Be sure to include your SPSS output (you will need to copy/paste the ANOVA table into a Word document first).

Phone Message

1.       What are the F statistics (in appropriate APA style) for:

1.       The main effect for Phone Message
2.       The main effect for Phone Type
3.       The interaction of Phone Message and Phone Type

2.       Regarding each of the above F statistics, what are your decisions for (alpha = .05):

1.       The main effect for Phone Message
2.       The main effect for Phone Type
3.       The interaction of Phone Message and Phone Type

3.       Do you need to test simple effects?
