Answer 1

24)

Value of the parameter =212/548=0.3869

Value of Statistics =20/100 =0.2

Population size =548

Sample size =100

31)

	Despramine	Lithium	Plaecbo	total
Yes	10	18	20	48
No	14	6	8	28
total	24	24	28	76

probability that the subject did not receive placebo =48/76 =0.6316

41) probability that the subject was on the placebo treatment or had a relapse =(48+8)/76 =0.7368

51) probability that the subject was in the placebo group given that there was no relapse into drug use =8/28 =0.2857
