STAT-S 300 Lecture Notes - Lecture 25: Sampling Distribution, Test Statistic, Randomized Experiment
Document Summary
The sampling distribution of: sampling distribution of. Confidence intervals for: when inference conditions met, approximate level c confidence interval for is: Significance tests for: hypothesized value- h0: p1 p2 = 0, alternative value- ha: p1 __ p2, test statistic- If h0: p1 = p2 is true, then both parameters are same. Common value - combine data from both samples. Combined sample proportion: two-sample z test for p1 p2. Random- data produced by random sample of size n from population 1 and random sample of size n from population 2 or by two groups of size n1 and n2 in randomized experiment. Normal- n1p1 > 10 n1(1 p1) > 10 n2p2 > 10 n2(1 p2) > 10: also correct to use above calculations with. Independent- in observational study without replacement, use 10% condition. In experiment, each subject"s response must not affect another subject"s.
