Document Summary
Soc 210 lecture 9 hypothesis testing (large samples) Hypothesis testing (large samples: statement about populations, explore whether the observed data can reject the hypothesis about the population with some probability. Step 2: state the null and research hypothesis. Z (obtained) = (ps p )/ ((p (1- p )/n)) 1/2. If z (obtained) does not fall in the critical region, then it fail to reject the null hypothesis, which stated that our population equals 0. 55, the difference is not significant. Polling and proportions questions to think about. Te probability of rejecting the bull hypothesis is a function of: the size of the difference, the value of alpha, the use of one- vs. two-tailed tests, the sample size (n) In hypothesis testing, difference that are otherwise trivial or uninteresting that are otherwise trivial or uninteresting may b significant. Hypothesis testing for means t test.
