There is an archaeological study area located in southwestern New Mexico. Potsherds are broken pieces of prehistoric Native American clay vessels. One type of painted ceramic vessel is called Mimbres classic black-on-white. At three different sites, the number of such sherds was counted in local dwelling excavations. Site I Site II Site III 68 23 14 30 19 38 20 55 67 19 68 22 81 10 50 19 23 Shall we reject or not reject the claim that there is no difference in population mean Mimbres classic black-on-white sherd counts for the three sites? Use a 1% level of significance. (b) Find SSTOT, SSBET, and SSW and check that SSTOT = SSBET + SSW. (Round your answers to three decimal places.)

Determine the relative unfairness of an appor- tionment that gives a new representative to Shasta rather than Hampton.
1 The Blue Tide High School Student Committee has 5 members. They would like to conduct a survey to get the students’ opinion on the school’s new bell schedule. They asked 23 students’ representatives to distribute a questionnaire to the schools’ 1550 students. In the end, they received 750 responses. They wrote a report based on the information provided by the respondents. 2) which number represents the size of the sample?

Please list your answers to part a, b, c, and d. Suppose you try to conduct a presidential approval poll of 5,000 likely U.S. voters. You know that 29% of the voters are registered as Republican, 34% are registered as Democrat, and 28% are registered as Independent. If you are going to construct a representative sample of this population, approximately how many of the likely voters in the sample should be: a. Republican b. Democrat c. Independent d. Notice the sum of the percents is not 100. What could account for this?
A survey of 1088 adults in a country, asking "As you may know, as part of its effort to investigate terrorism, a federal government agency obtained records from larger telephone and Internet companies in order to compile telephone call logs and Internet communications. Based on what you have heard or read about the program, would you say that you approve or disapprove of this government program?" Of those surveyed, 588 said they disapprove. a. Determine and interpret the sample proportion. b. At the 10% significance level, do the data provide sufficient evidence to conclude that a majority (more than 50%) of adults in the country disapprove of this government surveillance program? ..... a. The sample proportion is (Round to two decimal places as needed.) The sample proportion from this study is the proportion of adults in the that of the government surveillance program. b. What are the hypotheses for the one-proportion z-test? Ho: p= Ha:p (Type integers or decimals.) What is the test…
An art authenticator has a history of successfully identifying forgeries. Over her career, she has been asked to evaluate 74 actual forgeries and correctly identified 69 of them. Further, among all the authentic art she has looked at, she has never claimed any to be forgeries. An art dealer is considering purchasing a painting but is worried it is a fake. His experience in the field over the years indicates about 3% of the artwork he comes across is forged. a) If the dealer employs the services of the authenticator, and she indicates the painting is genuine, what is the chance it is actually a forgery? b) Without authentication, the dealer can sell the painting for $20,000. The price would increase to $25,000 if the painting were authenticated as genuine, but obviously it is worthless if it is deemed a forgery. The authenticator charges $2,000 for her services. Do you think it is worth it for the dealer to use the authenticator? Why or why not?
In 1998, as an advertising campaign, the Nabisco Company announced a "1000 Chips Challenge," claiming that every 18-ounce bag of their Chips Ahoy! cookies contained at least 1000 chocolate chips. Dedicated statistics students at the Air Force Academy (no kidding) purchased some randomly selected bags of cookies and counted the chocolate chips. Some of their data are given below. Complete parts (a) through (c) below. 1270 1244 a) Check the assumptions and conditions for inference. Check the data for independence. Choose the correct answer below. A. 0+ 900 1356 1132 Chips 1600 OA. The sample is less than 10% of the population, so one can assume that the data are independent. B.

The sample is less than 10% of the population, so one can assume that the data are not independent. Construct a histogram of the data. Choose…
Due to the popularity of instant messaging and social networking, informal elements such as emoticons (e.g., the symbol “:)” to represent a smile) and abbreviations (e.g., “LOL” for “laughing out loud”) have worked their way into teenagers’ school writing assignments. A Pew Internet and American Life Project (Apr. 2008) survey interviewed 700 randomly selected U.S. teenagers by telephone on their writing habits. Overall, 448 of the teenagers admitted using at least one informal element in school writing assignments. Recall that in a random sample of 700 teenagers, 448 admitted to using at least one informal element in school writing assignments. [Note: Emoticons, such as using the symbol “:)” to represent a smile, and abbreviations, such as writing “LOL” for “laughing out loud,” are considered informal elements.] Is there evidence to indicate that less than 65% of all U.S. teenagers have used at least one informal element in school writing assignments? Test the relevant hypotheses…
Another type of painted ceramic vessel is called three-circle red-on-white ( Mimbres Mogollon Archaeology). At four different sites in the Wind Mountain archaeological region, the number of such sherds was counted in local dwelling excavations.

Use a 10% level of significance. (a) What is the level of significance? State the null and alternate hypotheses. O Ho: H1 = H2 = H3 = H4i H1: Exactly three means are equal. O H.: H1 = H2 = H3 = Hại H,: Not all the means are equal. O H,: H1 = H2 = H3 = Ha; H;: All four means are different. O H.: H1 = H2 = H3 = Hại H: Exactly two means are equal.
