The graph in Figure 5 is called the ____, METHODS FOR OBTAINING AREA UNDER A NORMAL CURVE IF BETWEEN, METHODS FOR OBTAINING AREA UNDER A NORMAL CURVE, The notation zα (pronounced "z sub alpha") is the z-score such that the area under the standard normal curve to the ____ of zα is α. A trial with two mutually exclusive outcomes is known … In a school with 4400 females and 3800 males, the probability a randomly selected student is female is 0.537. A _____ has infinitely many values. A ∩ B = ∅, then A and B are said to be disjoint or mutually exclusive. The set of all possible outcomes for an experiment is called a sample space, and is denoted by S. ex. We denote events with one outcome, sometimes called simple events, as ____. 4.1 – Experiment, Outcomes, and Sample Space An experiment is a process that, when performed, results in exactly one of many observations. Experiments in which only two outcomes are possible are referred to as _____, provided that certain criteria are met. An experiment is composed of one or more trials. The values of a continuous random variable can be plotted on a line in an ____ fashion. buying 3 different cheeses out of 5 cheeses at super market. discrete probability distribution - The ____ of the ____ must equal one.
A combination is a collection, without regard to ____, in which r objects are chosen from n distinct objects with _≤_ _____ repetition. For example, for a normal random variable, P(a)=0 for any value of a because there is ___ area under the normal curve associated with a ____ value. A general rule of thumb, if the sample size n is no more than ____ of the population size N, we assume independence. Rather, it relies on ____ techniques. That is, the values of the random variable correspond to the outcomes of the random experiment. Probabilities: P(head) = 1 2 P(tail) = 1 2 Definition: The sample space of an experiment is the set of all possible outcomes of that experiment. It consists of ____ or ___ outcomes. These two outcomes are generally referred to as ____(such as making a free throw) and ____ (such as missing a free throw). Based on a survey of a random sample of 1050 young adults ages 18 to 24 years old conducted by a research center, the probability a randomly-selected 18- to 34-year-old lives with his or her parents is 0.321. What is P(E or F)? How many different simple random samples of size 5 can be obtained from a population whose size is 38?
Each individual outcome in the sample space is referred to as a sample point. : knowing that two events are disjoint means that the events are not ____. The probability distribution of a discrete random variable X provides the possible values of the random variable and their corresponding probabilities. A man has five shirts and five ties.
