Stats - Normal DistributionsAny Normal Distribution
Bell-shaped Symmetric about mean Continuous Never touches the x-axis Total area under curve is 1.00 Approximately 68% lies within 1 standard deviation of the mean, 95% within 2 standard deviations, and 99.7% within 3 standard deviations of the mean. This is the Empirical Rule mentioned earlier. Data values represented by x which has mean mu and standard deviation sigma. Probability Function given by Standard Normal DistributionSame as a normal distribution, but also ...
Mean is zero Variance is one Standard Deviation is one Data values represented by z. Probability Function given by Comprehension of this table is vital to success in the course!There is a table which must be used to look up standard normal probabilities. The z-score is broken into two parts, the whole number and tenth are looked up along the left side and the hundredth is looked up across the top. The value in th...
