Question: 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 32 reported that their physician communicated effectively. Determine the additional number of patients that need to be sampled to construct a 95?% confidence interval with a margin of error equal to 22?% to estimate this proportion. The additional number of patients that need to be sampled is ( ). ?(Round up to the nearest? integer.)
