EXERCISE 4.10 STRIKES AND THE ULTIMATUM GAME

A strike over pay or working conditions may be considered an example of an ultimatum game.

1. To model a strike as an ultimatum game, who is the Proposer and who is the Responder?

2. Draw a game tree to represent the situation between these two parties.

3. Research a well-known strike and explain how it satisfies the definition of an ultimatum game.

4. In this section, you have been presented with experimental data on how people play the ultimatum game. How could you use this information to suggest what kind of situations might lead to a strike?

Consumer Reports tested 11 brands of vanilla yoghurt and found these numbers of calories per serving:

130 160 150 120 120 110 170 160 110 130 90

Use a 0.05 significance level to test the claim that the mean serving is equal to 120 calories, as a diet guide claim.

1. State the hypotheses and identify the claim

2. Find the critical value or values

3. Find the test statistic. First state the calculator command used to find it.  

4. Make the decision about the null hypothesis

5. Draw conclusion about the claim

** Remember, there are examples in your notes at the end of each section**

The data set "cars" in R has 2 variables with 50 observations.
speed: numeric Speed (mph)
dist: numeric Stopping distance (ft)

Fill in the missing boxes below in the R code and then the corresponding predictor table from R.

Assume we want to test if dist a car travels can be determined by speed.

dat.lm = lm( __ ~ __ , data = __ )summary( __ )

a) Write the least squares line from the table above in the form ?̂= a + bx but filling the with the estimates of the coefficients.
?̂= __ + __x

b) Is there evidence to support that dist increases as the speed increases? Use ?=0.05.
1. ?₀ : ?₁ = 0 vs. ?? : ?₁> 0
2. ? = 0.05

3. t = __

4. Critical t_0.05,48 = t_0.05,40 = __

5. Conclusion:
Reject H0 OR Fail to reject H0

Interpretation:
There is sufficient evidence to support that dist increases as speed increases. OR
There is not sufficient evidence to support that dist increases as speed increases.

c) Find the 90% confidence interval for ?.

confint(dat.lm, 'speed', level = 0.90)

( __ , __ )

d) Find the 95% prediction interval for the mean when speed = 22.

newdat = data.frame( __ = __ )
predict( __ , __ , interval = 'prediction')

fit = __ , lwr = __ , upr = __

What are the beliefs about death and dying? How comfortable are people talking about your own mortality? How comfortable would a nurse be discussing their patient's mortality?

First, choose an ICS/SCADA system to depict. This may be a real or fictitious system. If it is a real system, please include citations for the organization and system design. Then, present the following sections in your paper:

• Introduction/System Organization: Describe the organization that owns the system. What is the name of the organization? How large is the organization? Where is the headquarters? Are there additional sites?
• Components: Explain the components of the system and include the network diagram in this section.
• Future Challenges: Examine the architecture of this system and identify significant vulnerabilities and risks. Be sure to document what you believe will be difficult to manage in terms of security for this system.

Discuss in detail the main characteristics and values of an encourager, paraphrase, and summarization?  What can you expect when you use encouragers, paraphrases, and summarizations? Explore why these are important skills to obtain for human service workers.

1. Weight Management and Body Composition
   1. State your feelings regarding your current body weight, considering what you have learned about body composition as well as body weight in pounds.
   2. Discuss why body composition is a more reliable measure of health than stepping on a scale.
2. Recommended Body Composition: (3 points)
   1. What is the recommended body composition (healthy % fat) for your a male at the age of 26?
   2. List one positive action step you can take to improve (or maintain) your body composition.

What were the main causes of the transition to capitalism in Europe? Compare Heilbroner and Marx on this issue. How was this transition related to the rise of modern political economy? Compare this relationship to the decline of classical political economy after 1830, according to Marx. Please explain in detail.
