Suppose that a new treatment is successful in curing a common ailment 69% of the time. If the treatment is tried on a random sample of 75 patients, approximate the probability that at most 54 will be cured. Use the normal approximation to the binomial with a correction for continuity.
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.
