Family Closeness. A study conducted among college students evaluated the connection between drug use and family closeness (the higher the score, the greater the family closeness). The sample mean on the family closeness scale was 2.0 (sample standard deviation =2.1) for 13 students who used drugs and 4.8 for 17 students who did not use drugs (sample standard deviation=3.2) a) Find the test statistic for comparing the means b) Construct a 95% confidence interval for the difference in family closeness for students who used drugs and students who did not use drugs. Interpret your confidence interval
