Z-score to determine the relative position of an observation. ( Z = X - / ) Central Limit Theorem: When the sample is sufficiently large (n30) the sampling distribution will be approximately a normal distribution. Confidence interval: Probability that the random selected interval encloses the unknown parameter. Typical values 99%, 95%, and 90%. Z-values large samples, t-values small samples, unknown. 90% : -1.65 95% : -1.96 99%: -2.58 +1.65 +1.96 +2.58 =SEM (std. error
