Preliminary analyses indicate that you can consider the assumptions for using nonpooled​ t-procedures satisfied. Researchers randomly and independently selected 28 prisoners diagnosed with chronic posttraumatic stress disorder​ (PTSD) and 23 prisoners that were diagnosed with PTSD but had since recovered​ (remitted). Obtain a ​95% confidence interval for the​ difference, ​, between the mean ages at arrest for prisoners with chronic PTSD and remitted PTSD

Look at this system of equations. -3x + 3y = 12 y = x + 4 the solution set of this system is best explained by which of these statements? a) the graphs of the equations are the same line because the equations have the same slope and the same y-intercept. the system has infinitely many solutions. b) the graphs of the equations are parallel lines because they have the same slope but different y-intercepts. the system has no solution. c) the graphs of the equations are lines that intersect at one point because the equations have the same slope but different y-intercepts. the system has exactly one solution. d) the graphs of the equations are lines that intersect at one point because the equations have the same slope and the same y-intercept. the system has exactly one solution.
