A study of bulimia among college women studied the connection between childhood sexual abuse and a measure of family cohesion (the higher the score, the greater the cohesion). The sample mean on the family cohesion scale was 1.9 for 11 sexually abused students (s= 1.8) and 5.2 for 24 nonabused students (s=3.7). a. Find the standard error for comparing the means. b. Construct a 95% confidence interval for the difference between the mean family cohesion for sexually abused students and non-abused students. Interpret. a. The standard error se= (Round to four decimal places as needed.)
