Was Hank's evaluation of the potential benefits of these systems realistic? What might research reveal about the most likely results of wireless data networks and customer support centres?

After identifying an unanswered question, a historian might form a hypothesis, an unproven answer to that question. Write a one sentence hypothesis to answer the following question: Why was Johnson more successful than Truman in getting civil rights legislation passed? Remember, your statement is not a fact but a theory that might or might not be supported by further research. The sentence you write could later become the thesis statement for a research paper.

Write a report on sources for a research project about nineteenth-century Russian society. Use the following question to focus your research: How might Sasha's place in Russian society have affected his behavior and expectations? Follow these steps to complete the assignment:

• Find three to four sources of varied types, including books, online material, and videos or other media.
• Evaluate the reliability of each source. Consider the date it was published, the author's credentials, and its accuracy.
• Write a summary of your findings, including a reason for or against using each source. Refer to a style manual to make sure you cite publication information for each source correctly.
• Then, write a preliminary answer to the focus question. List further research steps you would take to more fully answer the question.
• Present your summary and citations, preliminary answer to the focus question, and plan for further research in a slide presentation, poster, or essay form.

The American Economic Review (Mar. 2008) published research on how the gender mix of a U.S. legislator's children can influence the legislator's votes in Congress. Specifically, the researcher investigated bow having daughters influences voting on women's issues. The American Association of University Women (AAUW) uses voting records of each member of Congress to compute an AAUW score, where higher scores indicate more favorable voting for women's rights. The researcher modeled AAUW score (y) as a function of the number of daughters (x) a legislator has. Data collected for the 434 members of the 107th Congress were used to fit the straight-line model, $E(y)=\beta_{0}+\beta_{1} x$. Use the result to make an inference about the model.

You are the CEO of Widget World Corporation. Researchers have developed a new electronic widget. The fixed costs to make the widget will be $30,000, and the variable cost will be$150 per widget. The market research department conducted consumer surveys and reported the following results. In these ordered pairs, the first number represents the possible price and the second number represents the quantity demanded. The points are listed as (p, q). (75, 6,500), (100, 5,900), (125, 4,500), (150, 3,900), (175, 2,800), (200, 1,500), (225, 900). You now need to set up a demand function using the ordered pairs from the market research department. Enter these ordered pairs into graphing calculator lists. Write the linear regression equation that models this set of ordered pairs. Round each coefficient to the nearest integer.

English professor Jacob Bright has one typist, who types for 8 hours per day. He submits three types of jobs to the typist: tests, research papers, and class handouts. The information in Table 10 is available. Professor Bright has told the typist that tests have priority over research papers, and research papers have priority over class handouts. Assuming a nonpreemptive system, determine the expected time that Professor Bright will have to wait before each type of job is completed. TABLE 10:

$$\begin{matrix} \text{Type of Job} & \text{Frequency (number per day)} & \text{E(Si) (hours)} & E(S_{i}^{2}) (hours)^{2}\\ \text{Test} & \text{2} & \text{1} & \text{2}\\ \text{Research paper} & \text{0.5} & \text{4} & \text{20}\\ \text{Class handout} & \text{5} & \text{0.5} & \text{0.50}\\ \end{matrix}$$

An article found that Massachusetts residents spent an average of $\$ 860.70$ on the lottery in 2010, more than three times the U.S. average (www.businessweek.com, March 14, 2012). A researcher at a Boston think tank believes that Massachusetts residents spend less than this amount. He surveys 100 Massachusetts residents and asks them about their annual expenditures on the lottery.

c. At the $10 \%$ significance level, do the data support the researcher's claim? Explain.
