John just turned 12 (at t = 0), and he will be entering college 6 years from now (at t = 6). College tuition and expenses at State U. are currently $16,500 a year, but they are expected to increase at a rate of 3.5% a year. John is expected to graduate in 4 years. Tuition and other costs will be due at the beginning of each school year (at t = 6, 7, 8, and 9). So far, John’s college savings account contains $10,000 (at t = 0). John’s parents plan to add an additional $12,000 in each of the next 4 years (at t = 1, 2, 3, and 4). Then they plan to make 2 equal annual contributions in each of the following two years, t = 5,, and 6. They expect their investment account to earn 5.5%. How large must the annual payments at t = 5, and 6 be to cover John’s anticipated college costs?

1. You are starting your four-year college education today, and you are worried if you have enough money in your account for tuition and fees. You are going to pay $15,000 a year at the beginning of each school year starting today. If the interest rate on your account is 7%, compounded annually, how much should you have in your account today? Round to the nearest cent.

2. How much would an investor be willing to pay for an investment which promises to pay $200 per year in perpetuity if the investor requires a 14 percent return on the investment? Round to the nearest cent.

3. If you are going to receive $70,000 for 20 years starting 5 years from now, what is the present value of the cash flows discounted at 12%? Round to the nearest cent. (2 decimal)

This assignment covers two-sample hypothesis tests. As with Calculator HW 5, our goal is to understand the five step method of hypothesis testing, as well as the calculator functions.     Your work must include:

1. Clear statement of hypotheses, with the correct parameter(s)
2. An indication of the test used
3. The test statistic and p-value
4. An indication of the statistical decision (i.e. whether or not to reject Ho)
     along with an explanation.
5. An interpretation of the statistical decision in the context of the problem.

#1)   A sample of 12 in-state undergraduate school programs for State A has a mean tuition of $24,000 with a standard deviation of $4,600. In State B, a sample of 16 in-state undergraduate programs has a mean of $28,000 with a standard deviation of $5,200. Assume that in-state tuitions are normally distributed for both states. Using a .05 significance level, does this sample data provide evidence that the mean tuition are different for the two states?

PRECEDE-PROCEED model guides factors to consider when planning an intervention that is targeted towards the community/social level. It is a comprehensive model which identifies influences on a health problem at both the broad and proximal level. It is divided into two main activities educational diagnosis (PRECEDE) and ecological diagnosis (PROCEED).

PRECEDE: Predisposing, Reinforcing, and Enabling Constructs in Educational Diagnosis and Evaluation.

PROCEED: Policy, Regulatory, and Organizational Constructs in Education and Environmental Development.

There are nine phases to this model. These are:

1.Social diagnosis

2.Epidemiological diagnosis

3.Behavioral and environmental diagnosis

4.Educational and ecological diagnosis

5.Administrative and policy diagnosis

6.Implementation

7.Process evaluation

8.Outcome evaluation

9.mpact evaluation

plan a intervention for school children in regards to obesity

Give one example of each factor you might consider for Stages 1-5 of the PRECEDE-PROCEED model. Provide your rationale and supporting references for each factor.

Health problems of family members

The father has a chronic cough. Smoking (10 per day)

The mother's menstrual bleeding is irregular. She's afraid of getting pregnant again. He does not use a family planning method.

10-year-old child (girl) has very low school success, has no appetite and is poor (weight and height percentile 5%).

8-year-old boy has asthma. The family takes the child for control every 6 months (weight and height percentile 25%).

7-year-old boy healthy (weight and height percentile 10%).

5-year-old boy often gets bronchitis. When there is bronchitis, he has fever and cough (weight and height percentile 25%).

Develop a education material for each member of family  ( presentation / brochure / poster / etc.) suitable for the health education subject you have planned

1) μ: $3600 per student σ: $150 Distribution: Skewed to the left Draw a well-labeled picture of the relevant sampling distribution for this population data including its standardization (z), assuming the sample size is 1700 school districts.

2) On average college students are given homework 3 nights a week. The 95% Confidence Interval is reported as 2 to 6 nights. Answer the following true or false, and correct the “false” statements.  

a.         T    F     The width of a Confidence Interval depends on the sample size.

b.         T    F     You can know for sure that this interval includes the true population

                        parameter.

c.         T    F     This Confidence Interval is interpreted to mean that 95% percent of all 8^th

                        graders in the district are given homework 2 to 6 nights a week.

d.         T    F     The purpose of a Confidence Interval is to provide a range of values which are

                        thought to include the sample mean.

A sports psychologist is part of a team of researchers collecting descriptive psychological, mental, performance and physiological data on male and female high school athletes. One of the variables is Intelligence Quotient (IQ) as assessed by the Stanford-Binet Intelligence Scale (5^th Ed. 2003). A sample of athletes (n=61) provided the following statistics: mean±s_X = 97±16. The parameter µ for IQ is thought to be 100.   Test H₀: X=µ at α=0.05÷2 (a 2-tailed test).

Ted Bundy was a serial killer that was active from 1974-1978. He confessed to approximately 30 murders although the actual toll is unknown. Bundy targeted woman and was involved in kidnapping, rape, murder and necrophilia. He completed law school, worked on political campaigns, and outwardly appeared to many to be “normal”. When we thinking about profiling, can we see the signs for a future serial killer?   This week, we’ll explore the best ways to react to serial killers. Address the following prompts:


•   What is criminal profiling? How was it used in the Bundy case?
•   Discuss a few problems with profiling serial killers. Why are they hard to identify?
•   We see that they are many crimes that go unsolved (some suspected to be the work of serial killers). What challenges might investigators face in finding who committed a crime?
•   What are some treatment options for serial killers? In your opinion, do they work? (http://www.ncbi.nlm.nih.gov/pubmed/12613432)

1. Identify the type of test (chi-square, t-test, or ANOVA) that we have to use in each of the following scenarios. Explain why you chose that test.
   1. We want to compare males and females (gender) based on the difference in time spent on social media (measured as hours per day)

2. We want to compare our customers and the customers of our closest competitors based on their brand loyalty (measured as a Likert scale from 1 to 5)

• 3. We want to compare resident and commuter students based on differences in their gender (males and females)

4. We want to compare freshmen, sophomores, juniors, and seniors based on differences in time spent studying (hours per day)

5. We want to compare freshmen, sophomores, juniors, and seniors based on their willingness to recommend their school (simply measured as Yes/No).

6. We want to compare males and females based on their consumption of sugary drinks (ounces per day).

One of the most successful attacks against wireless networks (WLAN) is the Evil Twin attack. The goal is to introduce an attacker-controlled wireless access point near the “known good” WLAN network. This access point will advertise the exact same SSID as the authorized WLAN. Wireless users may accidently connect to this malicious access point thinking it is part of their authorized network. Once the connection is established, the attacker can initiate a man-in-the-middle attack and capture or relay traffic while eavesdropping on the entire communication.

Explain the potential risk an Evil Twin attack like this this would present, not in theory, but to your own organization (company, school, etc.) and how you would go about setting up an Evil Twin attack if you were an attacker. Detail the goals, tools, process, and methodology. Use whatever research will assist you. Provide screenshots if possible to demonstrate what you are doing. They can be third party
