- For unemployed persons in the United States, the average number of months ofunemployment at the end of December 2009 was approximately seven months(Bureau of Labor Statistics, January 2010). Suppose the following data are for aparticular region in upstate New York. The values in the first column show thenumber of months unemployed and the values in the second column show thecorresponding number of unemployed persons.MonthsUnemployedNumberUnemployed1 10292 16863 22694 26755 34876 46527 41458 35879 2325 10 1120Let x be a random variable indicating the number of months a person is unemployed.a. Use the data to develop an empirical discrete probability distribution for x.b. Show that your probability distribution satisfies the conditions for a validdiscrete probability distribution.c. What is the probability that a person is unemployed for two months or less?Unemployed for more than two months?d. What is the probability that a person is unemployed for more than sixmonths?You would like to conduct a cluster analysis with three binary variables. For all three of these variables, you can be sure that all of the observations coded "1" are similar to each other, and the observations coded "0" are similar to each other. Which distance measure should you use? Matching distance Manhattan distance Jaccard's distance Euclidean distanceAccording to the Pew report, 14.6% of newly married couples in 2008 reported that their spouse was of another race or ethnicity (CNNLiving, June 7, 2010). In a similar survey in 1980, only 6.8% of newlywed couples reported marrying outside their race or ethnicity. Suppose both of these surveys were conducted on 500 newly married couples.
