WebApr 23, 2024 · I have the following question from a stats course about binomial distribution: A multiple choice test has 10 questions, each with 5 possible answers, only one of which is correct. A student who did not study is absolutely clueless, and therefore uses an independent random guess to answer each of the 10 questions.
Quiz: The Binomial
The binomial test is useful to test hypotheses about the probability ($${\displaystyle \pi }$$) of success: $${\displaystyle H_{0}\colon \pi =\pi _{0}}$$ where $${\displaystyle \pi _{0}}$$ is a user-defined value between 0 and 1. If in a sample of size $${\displaystyle n}$$ there are $${\displaystyle k}$$ … See more In statistics, the binomial test is an exact test of the statistical significance of deviations from a theoretically expected distribution of observations into two categories using sample data. See more Suppose we have a board game that depends on the roll of one die and attaches special importance to rolling a 6. In a particular game, the die is rolled 235 times, and 6 comes up 51 times.

Probability to pass multiple-choice test, with two type of …
Web5. In a history class, Colin and Diana both write a multiple choice quiz. There are 10 questions. Each question has five possible answers. Wha t is the probability that . a) Colin will pass the test if he guesses an answer to each question. b) Diana will pass the test if she studies so that she has a 75% chance of answering each question correctly. WebChoice B is an example of a binomial random variable, because each die has the same probability of success (showing a value greater than 3) and there's a fixed number of trials. – – – In choice C the variable doesn't count the number of times a certain event happens, and so it is not a binomial random variable. ( 1 vote) Michele Franzoni WebFormula: n = number of trials k = number of successes n – k = number of failures p = probability of success in one trial q = 1 – p = probability of failure in one trial. Example: You are taking a 10 question multiple choice test. If each question has four choices and you guess on each question, what is the probability of getting exactly 7 questions correct? greater greenbrier chamber of commerce wv
