Postpartum depression and anxiety (PPD), is a common medical condition affecting mothers and their families after the birth of a baby. The CDC estimated that 19% of women who have recently given birth suffer from PPD. However, this research only reflected self-reported cases. Therefore, one group dedicated to helping women and their families with PPD believes that the true percentage of women who suffer from PPD is much higher. The group conducts a simple random sample of 135 women who had given birth in the last year and discovers that 34 of them report having PPD.
Required:
Based on this evidence, can the group claim that the true percentage of women who have PPD is greater than 19%?
