Overweight or obese adults from psychiatric programs were recruited and randomly assigned to a treatment group or control group. Patients in the treatment group received both weight-management sessions plus exercise sessions plus their usual care. Patients in the control group received their usual treatment for mental illness and no additional treatment. After 18 months, some of the patients had lost 5% or more of their weight, and some had not. The table summarizes the data. Complete parts (a) and (b) below. Treatment Group 46 Control Group 29 Lost 5% or more Did not lose 5% or more 88 106 ..... (a) Find the percentage of each group that lost 5% or more, and compare them descriptively. That is, report both percentages, and indicate what these sample percentages suggest about the effectiveness of the treatment program. Of the treatment group. % of them lost 5% or more. (Round to one decimal place as needed.) Of the control group, % of them lost 5% or more. (Round to one decimal place as needed.) Compare the two sample percentages.

State the null and alternative hypotheses. Choose the correct answer below. O A. Hg: Form of treatment and result have equal proportions. H3: Form of treatment and result have non-equal proportions. O B. Ho: Form of treatment and result are independent. Ha: Form of treatment and result are not independent. OC. Ho: Form of treatment and result have a p-value = 0.05. Ha: Form of treatment and result have a p-value # 0.05. O D. Ho: Form of treatment and result are not independent. Ha: Form of treatment and result are independent. Calculate the chi-square test statistic. x² = (Round to two decimal places as needed.) Use technology to find the p-value for this chi-square test. p-value = (Round to three decimal places as needed.) Use the p-value to form a conclusion.
