A clinical psychologist has conducted a test of a new therapeutic treatment for anxiety disorders in which the new therapy is compared against a no-treament control condition.Colleagues point out that more of the participants are dropping out of the control condition to seek treatment elsewhere.To see whether this is the case, the researcher collects a new sample of 200 people experiencing anxiety disorders.She then randomly assigns them to either a no-treatment control (Cond.1)or a treatment (Cond.2)condition and records whether participants stayed with the program (Gp 1)or left early (Gp 2).The results of a chi-square test are shown below (with output taken from Preacher's, 2001, on-line tool). Which of the following statements is true?
A)The program has not worked as p = .122.
B)The program has not worked because p .15
C)The result does not tell us whether the program worked.
D)The program has worked because chi-square 2.
E)None of the above.
