II and III

2.Suppose that 3% of the people in a group of adults have attempted suicide. Suppose a sample of 200 adults is selected at random from this group. The mean and the standard deviation of the sampling distribution for the sample proportion of the adults who have attempted suicide are (approximately):

= 0.03 and = 0.97

= 0.03 and = 0.012

= 0.03 and = 0.00015

= 0.97 and = 0.03
