Statistics Chpt6 Discrete Random Variables Docx Chapter 6 Ap statistics – chapter 6 notes§6.1 discrete and continuous random variables. random variables: a of some chance process. ex: (see introduction on page 340) in the ‘bottled water vs. tap water’ activity, 13 out of 21 students made correct identifications. Ap statistics chapter 6 – discrete, binomial & geometric random variables 6.1: discrete random variables random variable a random variable is a variable whose value is a numerical outcome of a random phenomenon. discrete random variable a discrete random variable x has a countable number of possible values. generally, these values.
Solved Chapter 6 Discrete Random Variables 1 Assume That Chegg Ap statistics chapter 6 random variables. recognize and define discrete random variables, and construct a probability distribution table and a probability histogram for the random variable. recognize and define a continuous random variable, and determine probabilities of events as areas under density curves. 6.1 discrete random variables read 340 344 what is a random variable? give some examples. what is a probability distribution? what is a discrete random variable? give some examples. alternate example: how many languages? imagine selecting a u.s. high school student at random. define the random variable x = number. While technology or the formula μx=∑[x•p(x)] can be used to calculate the mean of the random variable x, for this problem, use technology, rounding to one decimal place. μx=5.6 interpret the mean of the random variable x. the mean of a discrete random variable is the average outcome if the experiment is repeated many, many times. Move the “n” slider to n = 20. grab the “p” slider to see the role that p plays in the shape of the distribution. move the “p” slide to p = 0.2. let n increase from 10 to 60. describe what happens to the shape of the distribution as the number of trials, n, increases.

Example: apgar scores: babies’ health at birth (discrete random variables) in 1952, dr. virginia apgar suggested five criteria for measuring a baby’s health at birth: skin color, heart rate, muscle tone, breathing, and response when stimulated. she developed a 0 1 2 scale to rate a new born on each of the five criteria. In this video, you will be able to:1) identify if a random variable is discrete or continuous.2) create a probability distribution for a discrete random vari.
