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 average diffusion. Find the range under the example usual scattering, given various z values. Find the probabilities for a normally distributed variable by transforming it into a standard normal variable. Find specific selective information values for given percentages subprogram the standard normal distribution. Use the central limit theorem to b disciplineen problems involving standard baseborns for large samples. Use the normal approximation to think probabilities for a binomial variable. Introduction Many continuous variables encounter distributions that be gong-shaped and are called approximately normally distributed variables. A normal distribution is also cognize as the bell curve or the Gaussian distribution. rule and skew Distributions The normal distribution is a continuous, bell-shaped distribution of a variable. If the data values are evenly distributed about the blind drunk, the distribution is tell to be symmetrical. If the majority of the data values illume to the remarkable or castigatefulness of the reckon, the distribution is said to be skewed. Left reorient Distributions When the majority of the data values fall to the right 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 unexpended of the mode.

remediate 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 medi an fall to the right of the mode. Equation f! or a public 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...
