. In an online experiment, participants were asked to react to a stimulus. Upon seeing a blue screen, participants were instructed to press a key and the reaction time was measured in seconds. The same participant is also asked to press a key when seeing a red screen, with the reaction time measured. (The first color tested was randomly selected for each participant.) The results of 6 randomly sampled participants are below. Is the reaction time to the blue stimulus different from the reaction time to the red stimulus at the 1% level of significance? (assume the population differences are approximately normally distributed)

participant 1 2 3 4 5 6

blue 0.582 0.481 0.841 0.267 0.685 0.450

red 0.408 0.407 0.542   0.402 0.456 0.533

Conduct a full hypothesis test. Be sure to:

• state the test and calculator test

• check conditions

1. state the hypotheses

2. find the differences between the pairs, sample mean, sample standard deviation, degrees of freedom and calculate the test statistic

3. state the level of significance

4. find the p-value and draw/shade the graph

5. make a decision

6. write a conclusion

Find the future value of the following annuities. The first payment in these annuities is made at the end of Year 1, so they are ordinary annuities. Round your answers to the nearest cent. (Notes: If you are using a financial calculator, you can enter the known values and then press the appropriate key to find the unknown variable. Then, without clearing the TVM register, you can "override" the variable that changes by simply entering a new value for it and then pressing the key for the unknown variable to obtain the second answer. This procedure can be used in many situations, to see how changes in input variables affect the output variable. Also, note that you can leave values in the TVM register, switch to Begin Mode, press FV, and find the FV of the annuity due.)

Suppose all firms in a perfectly competitive and zero-fixed-cost industry previously in its long-run equilibrium are now receiving an upfront subsidy from the US government. Please use a graphic tool to answer the following questions: a) How do the MC and AC curve change due to this government intervention? b) At the current price, are the existing firms earn positive, negative, or zero profit? Identify the size of the profit/loss in the graph. c) Will we observe entry or exit in this industry as time goes by? d) What happens to the market price as the industry goes back to a long-run equilibrium? e) By how much each firm and the entire industry are producing in the long run? f) Draw the new long run industry supply curve in your graph. g) How do you think will the social welfare change?

Find an industry that is noted for consumer dissatisfaction. Using the concept of satisfaction, identify consumer expectations that aren’t being met along with describing their current experiences in this industry and how their experiences don’t meet their expectations. [Here, you want to first discuss the expectations and then, describe the actual experiences as a separate narrative.] Then, based upon what you have just characterized, how could you configure a business that would operate differently? Would it involve different expectations? If this is the case, how would your marketing be used in changing expectations? How would you change the consumer experience to be different based upon changing their expectations, etc.? How would you create a strategy involving a changing consumer?

Hint: Formally define the concept of satisfaction first by explaining the Expectancy Disconfirmation Model of Satisfaction and also, provide its graphic depiction.

You accepted a position at the company to lead a team of 3 multi-media developers (excluding yourself). This team will be responsible for graphic design, animations, and promotional material. Your role is to manage the team members, their hardware and software needs, and projects. Your employer asks you to assess the HARDWARE needs for the team and propose a computer configuration that would meet the functions of the team yet the least expensive.

Based on the information that you were given above (and not more), do your research (internet, friends, companies, etc…) and answer the following questions (briefly but at least close to 200 words):

What are the TOP two (2) MOST important computer parts you would need to consider for the team computers and why? (RAM, CPU, Graphics Card, Hard Drive, etc...) For these computer parts that you identified in the previous question, what general specifications would you recommend and why?
