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 Control Group Lost 5% or more 48 33 Did not lose 5% or more 84 112 Calculate the chi-square test statistic. x² = 9.82 (Round to two decimal places as needed.) Use technology to find the p-value for this chi-square test. p-value = 0.002 (Round to three decimal places as needed.) Use the p-value to form a conclusion. O A. Do not reject Ho. Form of treatment and result are not associated. O B. Reject H. Form of treatment and result are associated. O C. Do not reject Hn. Form of treatment and result are associated. O D. Reject Ho. Form of treatment and result are not associated.
