Outline of Chapter 6 text - Elementary Statistics: A Brief Version(A. Bluman 3rd Ed., 2003)

Chapter 6 Outline Identify disseminations as symmetrical or skewed. Identify the properties of the traffic pattern dispersal. Find the range under the monition standard distribution, given various z values. Find the probabilities for a normally distributed variable by transforming it into a standard normal variable. Find specific entropy values for given percentages intake the standard normal distribution. Use the central limit theorem to wreak problems involving standard baseborns for large samples. Use the normal approximation to enter probabilities for a binomial variable. Introduction Many continuous variables draw distributions that be cost-shaped and are called approximately normally distributed variables. A normal distribution is also cognize as the bell curve or the Gaussian distribution. pattern and skew Distributions The normal distribution is a continuous, bell-shaped distribution of a variable. If the data values are evenly distributed about the ba seborn, the distribution is state to be symmetrical. If the majority of the data values illume to the particular(a) or castigatefulness of the base, the distribution is said to be skewed. Left reorient Distributions When the majority of the data values fall to the amend of the mean, the distribution is said to be negatively or odd skewed. The mean is to the odd of the median, and the mean and the median are to the remaining of the mode.

decent Skewed Distributions When the majority of the data values fall to the left of the mean, the distribution is said to be positively or right skewed. The mean falls to the right of the median and both the mean and the median fall to the righ t of the mode. Equation for a linguistic ru! le Distribution The numeric equation for the normal distribution is: Properties of the Normal Distribution The shape and government agency of the normal distribution curve depend on deuce parameters, the mean and the...
