Chapter 6, Section 3-CI, Exercise 145 Are Errors Less Likely with Electronic Prescriptions?Errors in medical prescriptions occur and a study1 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.     Error No Error Total Electronic 254 3594 3848 Written 1478 2370 3848 Table 1 Are prescription error rates different? Find a 90% 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.The 90% confidence interval is Enter your answer; The 90%confidence interval, value 1 to Enter your answer; The 90%confidence interval, value…

You will conduct a study of 100 people with cancer to better understand people's view the role of nutrition in their cancer diagnosis and treatment. This mixed methods study will include quantitative data collection from all 100 persons and qualitative data collection from about 20 persons. Your aims to to describe: o Describe sources of information about cancer-related nutrition (who did they learn cancer- related information from?) o Assess knowledge about cancer-related nutrition o Understand nutrition-related behaviors people changed due to their cancer diagnosis or treatment State which aims would best be measured with quantitative data and which aims would best be measured with qualitative data. Explain why you would use quantitative or qualitative data collection for each.

USE DESCRIPTIVE STATS A report shows that Covid-19 reduced household expenditure in Europe by 8% in 2020. Elsewhere, consumer spending also dropped significantly in 2020, with 4% seen in the United States, and 17% reported in China (Broom, 2021).After reading the report, Mr. Goh, a student of Singapore University of Social Sciences, was interested to find out how Covid-19 has affected the household spending in Singapore. Surprisingly, he found news saying that consumer spending among Singapore residents was resilient and at a similar level to 2019 (Choo, 2021).In order to have a better understanding of the impact of Covid-19 on household spending of Singapore residents, Mr. Goh decided to conduct a survey. He got a random sample of 32 students from Singapore University of Social Sciences, and collected data on their average monthly household expenditure in 2019 and 2020. Based on his own experience, he hypothesised that the household expenditure of Singapore residents in 2020 is lower…
