In a 2010 study, teens with eating disorders were randomly assigned to receive either a new, family- based therapy (FBT) or the traditional therapy. Researchers wanted to determine whether the percentage of teens that maintain a healthy weight for a year is higher after receiving FBT than after receiving the traditional therapy. They tested HO:pFBT=pTraditional against Ha:pFBT>pTraditional, using a=0.05. They rejected their null hypothesis. Which of the following statements best expresses the conclusion of this hypothesis test? There is insufficient evidence to conclude that the proportion of teens that maintain a healthy weight after receiving FBT is less than the proportion of teens that do so after receiving traditional therapy. C There is sufficient evidence to conclude that the proportion of teens that maintain a healthy weight after receiving FBT is less than the proportion of teens that do so after receiving traditional therapy. C There is insufficient evidence to conclude that the proportion of teens that maintain a healthy weight after receiving FBT is about the same as than the proportion of teens that do so after receiving traditional therapy. There is sufficient evidence to conclude that the proportion of teens that maintain a healthy weight after receiving FBT is about the same as than the proportion of teens that do so after receiving traditional therapy. C There is insufficient evidence to conclude that the proportion of teens that maintain a healthy weight after receiving FBT is greater than than the proportion of teens that do so after receiving traditional therapy. C There is sufficient evidence to conclude that the proportion of teens that maintain a healthy weight after receiving FBT is greater than than the proportion of teens that do so after receiving traditional therapy
