Records from a city hospital say that the probability (p) that a confirmed dengue patient stays in the hospital for more than 5 days is 0.7. A new type of medicine claims fast recovery from the fever. A sample of 36 patients admitted with dengue fever is administered with the new medicine and 12 of them recover and leave the hospital within 5 days. (a) Construct a 95% confidence interval for p. (b) Would you conclude that the new medicine shortens recovery time?
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.
