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 18 % 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 119 women who had given birth in the last year and discovers that 28 of them report having PPD. Based on this evidence, can the group claim that the true percentage of women who have PPD is greater than 18 % ? Use a 0.10 level of significance. Step 3 of 3: Draw a conclusion and interpret the decision. Answer 田 Tables E Keypad Keyboard Shortcuts We reject the null hypothesis and conclude that there is insufficient evidence at a 0.10 level of significance that the true percentage of women who have PPD is greater than 18 %. We fail to reject the null hypothesis and conclude that there is sufficient evidence at a 0.10 level of significance that the true percentage of women who have PPD is greater than 18 % .
