It is known that 40% of mice inoculated with a serum are protected from a certain disease. Suppose you inoculate 60 randomly selected mice with this serum. Use the normal approximation with continuity correction to find following probabilities. a. What is the probability at least 40 mice contract the disease? b. What is the proabbility that more than 30 mice contract the disease?
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.
