A normal population has a mean of 80 and a standard deviation of 14. a. Compute the probability of a value 75 or less. b. Compute the probability of a value between 75 and 90. c. Compute the probability of a value greater than 70.
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.
