The U.S. National Highway Traffic Safety Administration gathers data concerning the causes of highway crashes where at least one fatality has occurred. From the 1998 annual study, the following probabilities were determined (BAC is blood-alcohol level):

?(???=0|Crash with fatality)=0.631P(BAC=0|Crash with fatality)=0.631

?(??? is between .01 and .09|Crash with fatality)=0.325P(BAC is between .01 and .09|Crash with fatality)=0.325

?(??? is greater than .09|Crash with fatality)=0.098P(BAC is greater than .09|Crash with fatality)=0.098

Suppose over a certain stretch of highway during a 1-year period, the probability of being involved in a crash that results in at least one fatality is 0.022. It has been estimated that 14% of all drivers drive while their BAC is grater than .09. Determine the probability of a crash with at least one fatality if a driver drives while legally intoxicated (BAC greater than 0.09).

The brightness of sunlight at the earth's surface changes over time depending on whether the earth's atmosphere is more or less clear. Sunlight dimmed between 1960 and 1990. After 1990, air pollution dropped in industrial countries. Did sunlight brighten? Here are data and scatterplot from Boulder, Colorado, averaging over only clear days each year. (Other locations show similar trends.) The response variable is solar radiation in watts per square meter.

No Yes What is the best word to describe the type of relationship? Curved Linear What is the correlation between the year and sun brightness (round your answer to at least two decimal places.)

According to the WHO MONICA Project the mean blood pressure for people in China is 128 mmHg with a standard deviation of 23 mmHg (Kuulasmaa, Hense&Tolonen, 1998). Blood pressure is normally distributed.

A.State the random variable.

B. Suppose a sample of size 15 is taken. State the shape of the distribution of the sample mean.

C. Suppose a sample of size 15 is taken. State the mean of the sample mean.

D.Suppose a sample of size 15 is taken. State the standard deviation of the sample mean.

E. Suppose a sample of size 15 is taken. Find the probability that the sample mean blood pressure is more than 135 mmHg.

F. Would it be unusual to find a sample mean of 15 people in China of more than 135 mmHg? Why or why not?

If you did find a sample mean for 15 people in China to be more than 135 mmHg, what might you conclude?

1) Describe and explain Davey’s (1969) J-curve theory of the “revolution of rising expectations.” What controversial conclusion does the theory suggest about the use (or non-use) of government means to achieve group equality?

2) List and briefly explain the findings of Pettigrew’s (1959; 1960) study of conformity and prejudice.  Who is most likely to express prejudice?  Who is least likely?  Why?

3)  Describe the relationship between religious orientation and prejudice.  Of what relevance are intrinsic and extrinsic orientations?  Explain “quest” and “fundamentalism,” and describe why they’re important.  Be sure to define all terms in your answer.

4) List and briefly explain at least four of the traits found in the authoritarian personality as measured by the F-Scale (Adorno et al. 1950)?  Which of these traits may also be found in Altemeyer’s (1998) “right-wing authoritarian”?  How does Altemeyer’s theory differ from that of Adorno et al.?  Be specific.

Solve the problem.

Income Measurement/Revenue Recognition A. Financial Accounting Standards Board (FASB) and the International Accounting Standards Board (IASB) came together on a unified project to outline the accounting principles for recognizing revenue and to develop a common revenue standard for U.S. GAAP and IFRS. Research IAS-18, Revenue, and discuss how it would apply to AMAZON. B. Review AMAZON's revenue over the past two years. Analyze the change in revenue (increase/decrease) and give the reasons for this change. C. Reflecting upon AMAZON's balance sheet, identify the unearned revenue accounts listed. How does AMAZON handle the proper accounting treatment with regard to recognizing revenue from unearned revenue accounts?

What I will be checking for is that you know which items should be classified as assets and which should be classified as liabilities, and that you know how to accurately calculate your net worth (Total Assets minus Total Liabilities).
