## Section-I:

Sampling and Sampling Distribution (Weight 2/10)

Sampling designs of Simple random, Stratified random, Systematic random and Cluster sampling, Judgment and Quota Sampling. Random Numbers and their use in sampling. Advantages of sampling. Probability and non-probability sampling, sampling and non-sampling errors, Calculation of sample mean, proportion and variance of simple random samples and stratified random samples. Sampling distribution of a statistic and its standard error. Sampling Distribution of mean, proportion, difference between two proportions and two means. Central limit theorem with illustration (Proof not required).

Statistical Inference (Weight 2/10)

Nature of statistical inference, point and interval estimation of parameter, properties of a good point estimator, confidence interval and its interpretation. Null and alternative hypotheses, simple and composite hypotheses. Type / and Type II errors. Level of significance. P-value and power of a test (only concept and definition), Acceptance and rejection regions, one sided and two sided tests, test procedure. Inference about single mean and difference between means for paired and un-paired observations. Inference about proportion and difference between two proportions. Determination of sample size. (Application of Normal distribution and t-distribution).

Introduction and application of Chi-square distribution: Interval estimation and test of hypothesis about population variance (Interval estimation for variance – single sample). Introduction and application of F-distribution: test of hypothesis for equality of two variance
