Bernoulli Trial - An experiment in which there are exactly two possible outcomes Binomial distribution - A random variable X represents the number of successes observed from the n Bernoulli trials Binomial Parameters - n = number of trials p = probability of success q = 1-p Binomial probability function (f(x)) - E[X] binomial function - E[x] = np var(x) binomial function - var(x) = npq MGF binomial function - Additive property of binomial function - Sum of independent binomially dist...

AP Statistics FlashcardsStatistic - correct answer is a single measure of some attribute of a sample parameter - correct answer a quantity (such as the mean or variance) that characterizes a statistical population and that can be estimated by calculations from sample data parameter - correct answer any factor that defines a system and determines its performance Parameters of equations - correct answer Uniform: min and max [also need to know whether distrib. is discrete or continuous] ...

Logistic Regression - Commonly used for modeling binary response data. The response variable is a binary variable, and thus, not normally distributed. In logistic regression, we model the probability of a success, not the response variable. In this model, we do not have an error term g-function - We link the probability of success to the predicting variables using the g link function. The g function is the s-shape function that models the probability of success with respect to the predict...

He measured 72 doors and found a mean width of 36.1 inches with a standard deviation of 0.3 inches. To test if the doors differ significantly from the standard industry width of 36 inches, he computes a z-statistic. What is the value of Joe's z-test statistic? 2.83 -1.81...
