An  urban economist wishes to test the claim that the distribution of United States residents in the United States is different today than it was in 1999.  In 1999, 19.6 % of the population of the United States resided in the Northeast; 23.0 % of the population of the United States resided in the Midwest; 35.4 % of the population of the United States resided in the South; 22.0 % of the population of the United States resided in the West.  The economist randomly selects 2000 households in the United States and obtains the frequency distribution below. Region Frequency Northeast 365 Midwest 404 South 752 West 479 Test the claim that the distribution of residents in the United States is different today from the distribution in 1999 at alpha = .05

The following is based on information from The Wolf in the Southwest: The Making of an Endangered Species, by David E. Brown (University of Arizona Press). Before 1918, the proportion of female wolves in the general population of all southwestern wolves was about 50%. However, after 1918, southwestern cattle ranchers began a widespread effort to destroy wolves. In a recent sample of 37 wolves, there were only 11 females. One theory is that male wolves tend to return sooner than females to their old territories, where their predecessors were exterminated. Do these data indicate that the population proportion of female wolves is now less than 50% in the region? Use α = 0.01. (a) What is the level of significance? State the null and alternate hypotheses. O Ho: P 0.5 O Ho: P = 0.5; H₁: p 5 and nq > 5. O The Student's t, since np > 5 and ng > 5. The standard normal, since np < 5 and nq < 5. O The Student's t, since np < 5 and nq < 5. What is the value of the sample test statistic? (Round…

Government economic studies reveal that young adults, not middle-aged or older adults, are having the most difficult time in today’s economy. Although the nation’s labor market shows a decline in the unemployment rate, the percentage of young adults, ages 18 to 24, currently employed (54 percent) is at the lowest level since the government data collection began in 1948. If you were working for a national survey organization doing a general public survey of young adults and older adults, what topics and questions would you design into your survey to elaborate on this finding?
