Problem set 2: use the following information to answer questions 4-7 (5 points total): We continue our analysis from previous problem set, this time examining the relationship between social class (CLASS) and spending on welfare (NATFARE). Social Class Spending on Welfare Lower Class Working Class Middle Class Upper Class Total Too little 54 34 8 244 About right 28 112 104 21 265 Too much 12 125 120 34 291 Total 94 321 322 63 800 4. What is the number of degrees of freedom for this table (1 pts)? 5. Calculate the chi-square (2 pts). Social Class/ Welfare f. - f.

Based on an alpha of .05, do you reject the null hypothesis (1 pts)? 7. Explain the reason for your answer (1 pts).Problem set 4: use the following information to answer questions 11-15 (15 points total): Let's examine the relationship between GNP per capita and the percentage of respondents willing to pay more in taxes. 11. In this chapter, we used Table 12.4 to illustrate how to calculate the slope and intercept in the regression table. Using table 13.4 as a model, create a similar table using the data below for GNP per capita and the percentage willing to pay higher taxes (5 pts). GNP per Capita (X) % Willing to Pay ( x - X ) ( Y - F ) ( x - X ) ( Y - F ) Higher Taxes (7] 20 86 21.22 25.6 26.58 17 14.56 13.8 37.55 15.43 1.88 18.7 4.62 33.52 28.8 15.8 15.7 33.5 30.12 24.6 11.52 18.9 3.77 25.3 16.5 24.8 29.82 17.14 36.83 31.32 14.67 18.59 EX=315.00 EY=406.00 IX= I= I= I= Mean X = EX / N = Please make sure you get the correct N and N is 16 in this data.

Data for three groups are presented based on the HINTS2012 data set. Present the five-step model for these data, using alpha = .01. QUALITYCARE is measured on a five-point scale: 1-excellent, 2-very good, 3-good, 4-fair, and 5-poor. Note how a lower score indicates a higher quality of care.

Make decision if alpha was set up at .05, and please use Appendix E (Page 381) to discuss your decision making (2 pts).12. From the table that you created in #11, calculate a, b, and write out the regression equation (i.e., prediction equation) (3 pts). 13.

About what percentage of citizens are willing to pay higher taxes for a country with a GNP per capita of 5.0 (i.e., $5,000)? For a GNP per capita of 35.0 (i.e., $35,000) (2 pts)
