For a group of 5 prisoners, are their scores on a criminal behavior survey correlated with their scores on a depression index? What is the correlation coefficient? What is the coefficient of determination? Criminal Behavior Scores Depression Scores 7 4 6 5 8 3 1 3 4 5 Correlation Coefficient: Coefficient of Determination: Question 2 What is the correlation between t 2 variables? What is the coefficien alienation? X Y 1 4 3 0 4 6 2 3 7 2 8 1 Correlation coefficient: Coefficient of Alienation: Question 3 5 pts Is the number of police deadly force incidents related to the number of police suicides? (I made these numbers up) Police Deadly Force Suicides 7 4 6 Police 2 2 5 3 6 2 Correlation coefficient: 1 Question 4 5 pts A random sample of 25 people in a large corporation has a mean of 75 and a standard deviation of 10 on a measure of work stress. The average score for the whole corporation was 81. Does the sample significantly differ from the population? Test at p = .05. df t-observed = t-critical = Does the sample significantly differ from the population? (Respond Yes/No): Question 5 5 pts A random sample of 10 students in Crim 4830 scored an average of 80 on their midterm with a standard deviation of 10. The average score for the entire class was 78. Does the sample significantly differ from the population? Test at .05. df= = t-observed = t-critical = Does the sample significantly differ from the population?
