In a study of the effectiveness of a fabric device that acts like a support stocking for a weak or damaged heart, 110 people who consented to treatment were assigned at random to either a standard treatment consisting of drugs or the experimental treatment that consisted of drugs plus surgery to install the stocking. After two years, 40% of the 60 patients receiving the stocking had improved and 32% of the patients receiving the standard treatment had improved. (Use a statistical computer package to calculate the P-value. Use Pexperimental - Pstandard. Round your test statistic to two decimal places and your Pivalue to four decimal places.) p Do these data provide convincing evidence that the proportion of patients who improve is higher for the experimental treatment than for the standard treatment? Test the relevant hypotheses using a significance level of 0.05. Yes O No
