The length, X, of a fish from a particular mountain lake in Idaho is normally distributed with μ=7.4 inches and σ=1.7 inches. (a) Is XX a discrete or continuous random variable? (Type: DISCRETE or CONTINUOUS) ANSWER: (b) Write the event ''a fish chosen has a length of over 4.4 inches'' in terms of X: (c) Find the probability of this event: (d) Find the probability that the length of a chosen fish was greater than 9.4 inches: . (e) Find the probability that the length of a chosen fish was between 4.4 and 9.4 inches: .
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.
