. Poverty In a study of how the burden of poverty varies among U. S. regions, a random sample of 1000 individuals from each region of the United States recently yielded the information on poverty (based on defining the poverty level as an income below $10,400 for a family of 4 people). The data are provided in the table to the right. (All the conditions are satisfied don't worry about checking them.) a. Write appropriate hypotheses. b. How many degrees of freedom? North Mid west west South West Total Poor 112 105 154 113 484 (121) (121) (121) (121) Not Poor 888 895 846 887 3516 (879) (879) (879) (879) Total 1000 1000 1000 1000 4000 x = 0.67+ 2.12+ 0.09+ 0.29+ 9.00+ 0.53 + 1.24+ 0.07 + = 14.01 P=0.0029 c. Suppose the expected values had not been given. Show exactly how to calculate the expected count in the first cell. d. State your complete conclusion in context. Car colors According to Ward's Communication, 19% of sports car enthusiasts prefer a red car, 16.2% silver, 14.7% black, 14.1% green, 14% white, and 22% other colors. A sample of 250 cars at a NASCAR raceway revealed 45 red cars, 42 silver cars, 34 black cars, 40 green cars, 39 white cars, and 50 other color cars. Are NASCAR color preferences typical of sports car enthusiasts? Test an appropriate hypothesis and state your conclusion. . Poverty In a study of how the burden of poverty varies among U.
