Independence. Total Probability Theorem and Bayes Theorem. Random variables (discrete and continuous). Distribution function. Probability function. Probability density function. Expected value of a random variable. Variance and standard deviation of a random variable. Theoretical distributions.STATISTICAL INFERENCE Sampling methods. Sample distribution of the mean. Confidence Intervals. Introduction to hypothesis testing. Validation of parametric test assumptions. Some parametric hypothesis tests. Main Bibliography Pedrosa, A.C., Gama, S.M.
