What is the probability of the rat making one error? The set of all possible outcomes of an experment is called the sample space. In each case, the random variable is ________ and can assume only ______ values, often denoted success and failure.. Flipping a coin once and noting whether it landed heads or tails or randomly sampling one person from a population of former students and noting whether he or she graduates is called a ___________ ________ or a __________ __________, The probability of observing a success on any given trial is denoted by _____, The probability of observing a failure on any given trial is denoted by ______, Success and failure are _______ exclusive and ________, p+q=1, Few __________ situations perfectly satisfy the characteristics of a Bernoulli trial, The last 2 characteristics of a Bernoulli trial are satisfied only when sampling is done _______ replacement or from an _______ population, In most research, sampling is done __________ from a ________ population, This practical departure from the ideal is of little consequence as long as the population is ________ relative to the sample size, When there are __ Bernoulli trials, the random variable of interest is the number of __________; its value can range from 0 to n, All Bernoulli distributions are _________ but not all binomial distributions are ____________ distributions, A binomial distribution is a relatively simple example of an important class of ____________ distributions or models that are referred to as ____________ distributions, The term __________ _________ is the special name given to a probability distribution where the random variable is a statistic based on the results of more than one trial, The number of successes observed on ________ identical Bernoulli trials is called a ___________ random variable, The probability distribution of a binomial random variable is a _________ ____________, The probability of observing exactly r heads (successes) in n tosses is given by the ________ ________.

As n increases, the shape of the distribution approaches more and more closely that of the _________ ___________ distribution. Outcome: The result of a random experiment is called an outcome.

How is X the expected value computed for a continous random variable? The set of all possible outcomes is called the sample space. Random Experiment: A random experiment is one in which all the possible results are known in advance but none of them can be predicted with certainty. E(X) is the _______ of a ___________ population defined by its probability distribution. The mean of ungrouped frequency distribution. How many different ways can a rat traverse a maze if the correct series of turns is right, left, right? Let H represents heads and T represent tails. Most researchers prefer to use a table of _____ _______ to draw their random samples. Suppose an experiment consists of a coin 2 times. The expected value of a ___________ random variable is more complicated because the variable can assume an infinite number of values. Sample Space: The set of all the possible outcomes of a random experiment is called Sample Space, and it is denoted by ‘S’. All of the possible outcomes of an experiment form the elements of a sample space.

In terms of probability, the important fact about a coin is simply that when tossed it lands on one side or the other. | 1. © 2003-2020 Chegg Inc.
