• To learn the applications of statistics in business decision making.
UNIT I INTRODUCTION
Basic definitions and rules for probability, conditional probability independence of events, Baye’stheorem, and random variables, Probability distributions: Binomial, Poisson, Uniform and Normal distributions.
UNIT II SAMPLING DISTRIBUTION AND ESTIMATION
Introduction to sampling distributions, sampling distribution of mean and proportion, application of central limit theorem, sampling techniques. Estimation: Point and Interval estimates for population parameters of large sample and small samples, determining the sample size.
UNIT III TESTING OF HYPOTHESIS – PARAMETIRC TESTS
Hypothesis testing: one sample and two sample tests for means and proportions of large samples (z-test), one sample and two sample tests for means of small samples (t-test), F-test for two sample standard deviations. ANOVA one and two way.
UNIT IV NON-PARAMETRIC TESTS
Chi-square test for single sample standard deviation. Chi-square tests for independence of attributes and goodness of fit. Sign test for paired data. Rank sum test. Kolmogorov-Smirnov – test for goodness of fit, comparing two populations. Mann – Whitney U test and Kruskal Wallis test. One sample run test.
UNIT V CORRELATION AND REGRESSION
Correlation – Coefficient of Determination – Rank Correlation – Regression – Estimation of Regression line – Method of Least Squares – Standard Error of estimate.
