The fear of negative evaluation (FNE) scores for 11 female students known to suffer from the eating disorder bulimia and 14 female students with normal eating habits are presented below. In this question, we will compute a 95% confidence interval for µ1 −µ2, the difference of the population mean FNE scores for bulemic and normal female students respectively. Bulimic Normal 21 21 13 18 13 24 6 11 10 13 16 19 20 14 13 7 25 8 10 19 19 15 16 23 20 (a) Treating the bulimic and normal groups as populations one and two respectively, calculate ¯y1, s1, y¯2 and s2. You can just write out these values. You do not need to copy and paste the code. (b) Calculate sp and the standard error of ¯y1 − y¯2. (c) Provide the appropriate t-curve critical value for constructing a 95% confidence interval for µ1 − µ2. (d) Provide a 95% confidence interval for µ1 − µ2.
