The Pew Research Center (2021) conducted a survey to learn more about how people in the United States think about voting rights. They were particularly interested in learning if there are group differences in whether people viewed voting as a, “Privilege that comes with responsibilities and can be limited” or a, “Fundamental right for every U.S. citizen and should not be restricted.” They found differences in these perspectives between the two leading political parties, with more Democrats reporting that they viewed voting as a fundamental right compared to Republicans. However, they were also interested in determining if there were differences between different racial/ethnic groups and compared the responses of white, Black, Hispanic, and Asian survey respondents. What statistical test should be used to determine if there are differences between the surveyed racial/ethnic groups? Assume parametric assumptions are met.   A. Is this a relationship test or a difference test? Explain your rationale.   B. What would be the appropriate statistical test? Explain your rationale

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.) SSTOT =   SSBET =   SSW =   Find d.f.BET, d.f.W, MSBET, and MSW. (Round your answers for MSBET, and MSW to two decimal places.) d.f.BET =   d.f.W =   MSBET =   MSW =   Find the value of the sample F statistic. (Round your answer to two decimal places.)What…

2.    The Department of Fish and Wildlife looked at the ages of individuals between 65 and 81 that frequented the Bolsa Chica Reserve during the week of June 13th, 2021, to help determine if more facilities and resources are necessary to support the needs of that age group. They determined there were 40 individual visitors that fit those criteria, with the following ages: 65, 66, 66, 67, 67, 67, 68, 68, 68, 68, 69, 69, 69, 69, 69, 69, 70, 70, 70, 70, 70, 71, 71, 71, 71, 72, 72, 72, 73, 73, 73, 74, 74, 75, 75, 76, 77, 78, 79, and 80. Age (years) Number of Visitors 65 1 66 2 67 3 68 4 69 6 70 5 71 4 72 3 73 3 74 2 75 2 76 1 77 1 78 1 79 1 80 1 81+ 0   What would you say is the best measure of central tendency for the weekly visitor distribution? How should the Department of Fish and Wildlife report it? Justify your response.
