In a randomly selected sample of 2237 US adults, 1754 identied themselves as people who use the Internet regularly while the other 483 indicated that they do not use the Internet regularly. In addition to Internet use, participants were asked if they agree with the statement \"most people can be trusted.\" The results show that 807 of the Internet users agree with this statement, while 130 of the non-users agree.1 Find a 95% condence interval for the difference in the two proportionspl pN, where pl is the proportion for the internet users who agree with the statement and pN is the proportion for the non-internet users who agree with the statement. Round your answers to three decimal places. The 95%condence interval is n I to n 1Hampton, K., Goulet, L.

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.

Find a 99% confidence interval for the difference in the two proportions, Pw - Pe, where Pw is the proportion of errors using written prescriptions and Pe is the proportion of errors using e-prescriptions. Round your answers to three decimal places.
