FOr the below circumstances, describe if each random variable is binomial, poisson, bernoulli, or none of these, and a brief reason why: you give a test with 15 questions to people to assess their knowledge of what actions will do the most to help the environment. Each is right or wrong. X is the number of questions a person answers correctly. X is the number of eggs laid by a lionfish in one spawning (i.e. in one laying event) (mean 30,000!) You sample fish from a lake, one at a time on a fishing line. X is the number of fish you sample until you catch your first invasive snakehead fish.
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.
FOr the below circumstances, describe if each random variable is binomial, poisson, bernoulli, or none of these, and a brief reason why:
-

X is the number of eggs laid by a lionfish in one spawning (i.e. in one laying
event ) (mean 30,000!) -
You sample fish from a lake, one at a time on a fishing line. X is the number of fish you sample until you catch your first invasive snakehead fish.
-
An urn contains 20 red balls and 30 white balls. You draw out 10 balls at random WITHOUT replacement. X is the number of red balls in your sample.
-
X is the number of times you die each day.
