Relative Risk = (27*44) / (7*66) = 1188 / 462 = 18/7 or approx. 2.5714

Odd’s Ratio = (27*37) / (7*39) = 999 / 273 = 333/91 or approx. 3.6593

Relative Risk = (7*251) / (22*39) = 1757 / 858 or approx. 2.0478

Odd’s Ratio = 1603 / 704 or approx. 2.2770

a.) What is the prevalence of Hypertension at the start of the trial? 100%

b.) What is the Prevalence of Hypertension at the end of the trial? 80%

c.) Estimate the relative risk comparing the proportions who are free of hypertension at 12 weeks between groups. Relative Risk= 3/7 or 0.4286

Are you good with statistics? Part A: Exploratory Data
Part A: Exploratory Data Analysis Preparation Open the files for the course project and the data set. For each of the five variables, process, organize, present and summarize the data. Analyze each variable by itself using graphical and numerical techniques of summarization. Use Excel as much as possible, explaining what the results reveal. Some of the following graphs may be helpful: stem-leaf diagram, frequency/relative frequency table, histogram, boxplot, dotplot, pie chart, bar graph. Caution: not all of these are appropriate for each of these variables, nor are they all necessary. More is not necessarily better. In addition be sure to find the appropriate measures of central tendency, the measures of dispersion, and the shapes of the distributions (for the quantitative variables) for the above data. Where appropriate, use the five number summary (the Min, Q1, Median, Q3, Max). Once again, use Excel as appropriate, and explain what the results mean. Analyze the connections or relationships between the variables. There are ten possible pairings of two variables. Use graphical as well as numerical summary measures. Explain the results of the analysis. Be sure to consider all 10 pairings. Some variables show clear relationships, while others do not. … read more
