The MCAT, Medical College Admissions Test, must be taken by students wishing to gain entrance to most Medical Programs in Canada and the United States. There are four sections: Physical Sciences (PS), Verbal Reasoning (VR), Biological Sciences (BS), and Writing Sample (WS). The First three are each scored on a scale from 1 to 15, with a mean of 8 and a standard deviation of 2.

(a)Determine the percentile ranks for the following students:

(b)If a Medical School sets a requirement that students who will be considered must have a score of 10 on the Physical Science, 12on the Verbal Reasoning and 11 on the Biological Sciences Sections, what proportion of the population will qualify for each portion of the test?

3.The ACT, American Colleges Test, is comparable to the SAT ReasoningTest. The ACT is well modeled by a normal distribution, X~ N(21, 52),whereas the SAT Reasoning Test is modeled by S~N(1500, 3002). A college will accept either the SAT or the ACT for admissions. A college admissions assistant needs to compare the following two students to each other though they wrote different tests. How would the admissions assistant do this? Which student seemed to score better?

Matthew Chant ACT Score = 27

Joseph BellSAT Score = 2050

List at least 3 environmental and lifestyle factors that you personally think have contributed the most to America's overweight and obesity trend. Make sure to explain why you think your choices are the top three.

• Some environmental/lifestyle factors to consider include:
  • Food environment, portion sizes, home-cooked meals vs take out, restaurants
  • Emotions, stress, sleep habits, prescription drug use, smoking cessation
  • Sedentary lifestyle, television, the community environment, etc.
  • Why is the government so concerned with the growing obesity trend in the United States? What are they doing about it?
  • What do you think would be the best strategy to stop the obesity trend in the US? List two changes you would make if you were in charge of your community.  
  • Consider your own weight and caloric intake. View your NutriCalc Plus reports. Do you typically meet your DRI energy recommendations? Is your energy (calorie) intake too low, or too high? Are you able to maintain a healthy weight with your current intake?  
  • What strategies do you use to maintain a healthy weight? If you are not at a healthy weight (underweight or overweight), what factors are most challenging to you as you seek to achieve and maintain a healthy weight?  

The General Social Survey is an annual survey given to a random selection of about 1500 adults in the United States. Among the many questions asked are "What is the highest level of education you've completed?" and "If you're employed full-time, how many hours do you spend working at your job during a typical week?"

In a recent year, 1099 respondents answered both questions. The summary statistics are given in the chart below. (The sample data consist of the times, in hours per week, that were given by the respondents.)

To decide if there are any differences in the mean hours per week worked by these different groups, we can perform a one-way, independent-samples ANOVA test. Such a test uses the statistic

F= Variation between Samples/ Variation within the samples

Mila De Jong is your client. She has emigrated from the Netherlands and has lived in the United States for the last 10 years. She is a naturalized U.S. citizen. Mila owns a small flower shop, which she runs as a sole proprietorship and reports her earnings on Schedule C. Mila usually keeps her receipts in a digital file and brings you a Excel spreadsheet in which she tracks her income and expenses by month for the year.

However, Mila does not understand the U.S. tax system and laws very well because in the Netherlands, there is a Value-Added Tax (VAT) system in which you can either deduct items or you cannot. She is not used to the “either or” scenario that standard deductions and itemized deductions present.

She has an appointment to come to your office this week. However, she will not be alone. She will be bringing her recently naturalized parents and her brother to file their tax returns as well. They too are equally confused about U.S. tax law. Excited at the prospect of two new returns that you can charge for, you decide to create a PowerPoint presentation for the family to explain things.

Explain the following points.

• Determining net business income and how it translates to personal income
• The rules governing the difference between standard and itemized deductions

1. What could cause a shift in the (U.S.) demand for British pounds?

a. 10 cents.

b. $1.

c. $10.

d. $100

e. $1000.

Many people assume that when employers economize on safety programs the money they save improves profits, but that’s not the case. For one thing, poor safety practices raise wage rates, because wage rates are higher on jobs with riskier working conditions, other things equal. And poor safety and the injuries and illnesses it begets actually drive up costs, including medical expenses, workers’ compensation, and lost productivity. Consider the evidence. One study found a 9.4% drop in injury claims and a 26% average savings on workers’ compensation costs over 4 years in companies inspected by California’s occupational safety and health agency. A survey of chief financial officers concluded that for every one dollar invested in injury prevention, the employer earns two dollars; 40% said “productivity” was the top benefit of effective workplace safety. One forest products company saved over $1 million over 5 years by investing only about $50,000 in safety improvements and employee training. In the United States, work-related hearing loss costs employers about $242 million a year in workers’ compensation claims alone, costs that are probably avoidable through earmuffs, earplugs, and training. So one of the easiest ways to cut costs and boost profits is to spend money improving safety.

Assuming this is true, why do so many employers apparently cut corners on safety?

Activity 2

Record your data from Activity 1 in the boxes below. Place the data (turbidity value, appearance) for the samples in the appropriate columns (clean standard,           maximum load, standard, sample 1, sample 2, sample 3)

The following information will be needed to make your conclusion --

In the region of the United States you are investigating, the allowable standards of turbidity are:

Drinking water is 0.3 NTU

Water for irrigation and industrial use 5 NTU

Water released into lakes is 10.0 NTU

Water released into rivers 15.0 NTU

PLEASE ANSWER ALL QUESTIONS THANK YOU!

1. Is the turbidity spectrometer accurate based on the data from the Clean Water and Maximum Load Water Standards?

Explain why or why not?

2. Is the relationship between the appearance of the sample and the NTU value of each sample consistent for all samples?

Explain why or why not.?

3. For each sample, make a recommendation for the best way to release or use the waste water based on the Turbidity Stands Chart.
