. A manager for an insurance company believes that customers have the following preferences for life insurance products: 40% prefer Whole Life, 10% prefer Universal Life, and 50% prefer Life Annuities. The results of a survey of 310 customers were tabulated. Is it possible to refute the sales manager's claimed proportions of customers who prefer each product using the data?

Suppose CPI is as follows in each year:

Suppose in the year 2007 you are considering a job offer that pays $50,000 in 2007, plus a 10% (compounding) raise in each of the next three years.

Suppose in the year 2007 you are considering a job offer that pays $50,000 in 2007, plus a 10% (compounding) raise in each of the next three years.

1. What nominalsalary will you make in each year?

2. What will your real salary be in each year, using a 2007 base year?

3. What will your real salary be in each year, using a 2009 base year?

4. In what year was your real salary highest?                                 _________
5. Does your answer to 4 depend on the base year selected?        _________
6. Suppose instead your contract gave you $50,000 in 2007, plus a cost of living adjustment equal to the percentage change in CPI. Compute the nominal wage in each year.

7. In what years is this contract better than the original one?       _________

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?  

Then, answer the following questions about the System on a Chip (SOC) and Package on Package (POP) that the RPi implements:
1. The Broadcom SoC is installed in a large range of devices. Explain what the advantages are of having a System on a Chip rather than a separate CPU, GPU, and RAM components.
2. What are the disadvantages to a SOC style chip?
3. Explain using step-by-step instructions how the CPU executes a simple program such as adding two whole (integer) numbers together. You should refer to the Control Unit, RAM, cache, registers, and the Arithmetic Logic Unit in your explanation. You should also be able to name the roles of some of the registers.
4. What is the basic difference between a SOC and a POP? Which method was used to include the RAM on the R-Pi?
5. Where does one typically find SOC and POP type chips?
6. What are some of the instructions that make up the Instruction Set Architecture of the Broadcom ARM chip in your Raspberry Pi? An example we’ve used in class is ADD, list at least 5 others. Does it use a RISC or a CISC instruction set?
7. What are some of the named registers in your Broadcom ARM Chip on your Raspberry Pi?
8. How much level 1, level 2, and level 3 cache does your CPU in the Raspberry Pi have access to?

Suppose that the price of sugar, a major input for making Coca – Cola (Coke), decreased. Using two separate competitive supply/demand diagrams for Coke market, and Pepsi market, illustrate and briefly explain the probable effects of the decrease in the price of sugar: on equilibrium price, and equilibrium quantities, in the Coke and Pepsi market (assume Pepsi uses sweetener instead of sugar). What happens to the revenues of Coke, and Pepsi producers/sellers? [Hint: Coke and Pepsi are substitutes]. You may just explain in detail what happens to the demand/supply curves for Coca – Cola market and Pepsi market as well as corresponding equilibrium price and quantity
