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, 45% of the 60 patients receiving the
stocking had improved and 30% of the patients receiving the
standard treatment had improved. Do these data provide convincing
evidence that the proportion of patients who improve is higher for
the experimental treatment than for the standard treatment?
(Use pexperimental − pstandard. Round
your test statistic to two decimal places and
your P-value to four decimal places.)
