These data are taken from a study on army veterans. The subjects classified according to whether they had served in Vietnam (yes-no), and whether they had sleep problems (yes-no). Sleep Problems Service in Vietnam Yes (Y = 1) No (Y = 2) Total Yes (X = 1) 173 599 772 No (X = 2) 160 851 1011 Total 333 1450 1783 Compute estimated sleep problem probabilities for each group (Please Show All Work): p1= ___________; p2 = __________ Give the sample Relative Risk and Odds Ratio (Please Show All Work)
Contingency Table
A contingency table can be defined as the visual representation of the relationship between two or more categorical variables that can be evaluated and registered. It is a categorical version of the scatterplot, which is used to investigate the linear relationship between two variables. A contingency table is indeed a type of frequency distribution table that displays two variables at the same time.
Binomial Distribution
Binomial is an algebraic expression of the sum or the difference of two terms. Before knowing about binomial distribution, we must know about the binomial theorem.
