In this assignment, you will calculate the relative risk, attributable risk, and number needed to treat for a contrived clinical research study. In the study, researchers want to determine whether a new drug will reduce the risk of blood clotting in patients who have been diagnosed with blood clots in the past. 2,000 participants were selected for the study. 1,000 participants were given the new drug, and 1,000 participants were given a placebo. After 5 years, the number of participants from each group who had developed a blood clot were recorded. The data is shown in the table below. 1. Calculate the RR, ARR, and NNT for the data. 2. Briefly interpret each value in your own words.   Blood clot No blood clot Total New drug 21 979   Placebo 45 955   Total

Create a side-by-side boxplot for vitamin D level vs. NewAge and a side- by-side boxplot for vitamin D level vs. country. Create a scatterplot to show the relationship between vitamin D level and Age. Compare these two side-by-side boxplots and the scatterplot and explain your findings. • Note: Write appropriate captions for the tables, graphs, and outputs.

Several years ago, two companies merged. One of the concerns after the merger was the increasing burden of retirement expenditures. An effort was made to encourage employees to participate in the 401(k) accounts. Nationwide, 63% of eligible workers participated in these accounts. The accompanying data table contains responses of 30 employees of the company when asked if they were currently participating in a 401(k) account. Complete parts a through d. Click the icon to view the data table. a. Determine the sample proportion of company workers who participate in 401(k) accounts. The sample proportion is. (Round to three decimal places as needed.) b. Determine the sampling error if in reality the company workers have the same proportion of participants in 401(k) accounts as does the rest of the nation. The error is (Round to three decimal places as needed.) c. Determine the probability that a sample proportion at least as large as that obtained in the sample would be obtained if the…
