Please answer these questions in the unit 6 discussion board and place your answers on the board. Refer to the data below to answer your questions.

Question 1) Looking at the frequencies table- for the pct1824 variable- in what range do 68% of the cases fall?

Question 2) Looking at the frequencies table- for the income variable- in what range do 95% of the cases fall.

Question 3) Looking at the frequencies table- for the density variable- in what range can I be 95% sure where the population mean falls?

Question 4) In the cross-tabulations table- cities in the south = 1 and cities outside the south = 0- and cities that have collective bargaining in police= 1 and those that do not = 0. If my hypothesis was that cities in the South are more likely to have collective bargaining than those outside the South- did I find for my hypothesis? Why or why not?

Question 5) In the chi-square test- is there a statistically significant relationship between South and Collective Bargaining?

Question 6) According to the difference in means test- cities with a mayor/ city council form of government =1 and those with other structures = 0. If my hypothesis is that cities with mayor city forms of government have higher forms of spending- did I find for my hypothesis? Why or why not?

Question 7) In the correlation coefficient table- What is the relationship between density and poliexp?

Question 8) Looking at the regression analysis- What percentage of the dependent variable of COPS is explained by the independent variables?

Question 9) What is the relationship in the regression analysis between density and COPS?

Question 10) If cities with police unions = 1 and those without = 0, then what is the relationship between police unions and COPS?

Question 11) What are some extraneous variables that have not been included in this regression analysis that may impact the number of police (COPS) per 100,000?
