Current Attempt in Progress Are Errors Less Likely with Electronic Prescriptions? Errors in medical prescriptions occur and a study examined whether electronic prescribing may help reduce errors. Two groups of doctors used written prescriptions and had similar error rates before the study. One group switched to e-prescriptions while the other continued to use written prescriptions, and error rates were measured one year later. The results are given in Table 1 No Error Total Error Electronic 254 3594 3848 Written 1478 2370 3848 Table 1 Are prescription error rates different? Find a 95% confidence interval for the difference in the two proportions, Pw - Pe, where p,, is the proportion of errors using written prescriptions and p, is the proportion of errors using e-prescriptions. Round your answers to three decimal places. The 95% confidence interval is i to i Is it plausible that there is no difference
