Suppose a hospital would like to estimate the proportion of patients who feel that physicians who care for them always communicated effectively when discussing their medical care. A pilot sample of 50 patients found that 40 reported that their physician communicated effectively Determine the additional number of patients that need to be sampled to construct a 99% confidence interval with a margin of error equal to 8% to estimate this proportion The additional number of patients that need to be sampled is 23.46 (Round up to the nearest Integer)
