Course Description

Course objectives:

To impart the theoretical as well as practical knowledge of estimation, testing of hypothesis,

application of parametric and non-parametric statistical tests, design of experiments, multiple

regression analysis, and basic concept of stochastic process with special focus to data/problems

related with computer science and information technology.


Units and Unit Content

2. Testing of hypothesis
teaching hours: 8 hrs

Types of statistical hypotheses; Power of the test, concept of p-value and use of p -value in

decision making, steps used in testing of hypothesis, one sample tests for mean of normal

population (for known and unknown variance), test for single proportion, test for difference

between two means and two proportions, paired sample t-test; Linkage between confidence

interval and testing of hypothesis
