HO: μ1 = μ2 HA: μ1 ≠ μ2 Understand the nature of a hypothesis test, the difference between one-tailed and two-tailed tests, and the terms null hypothesis, alternative hypothesis, significance level, rejection region (or critical region), acceptance region and test statistic HYPOTHESIS TESTING (ONE SAMPLE)CHAPTERPREVIOUSLY •used confidence intervals to answer questions such as You know that % of women have red/green color blindness. Is the work output of state workers is different from that of workers in the private sector? Make sure you understand this point  Formulate the hypothesis to be tested. Comparison of test statistic to critical region to draw Research Question. Assumptions. Hypothesis test: A one-sample z-test for proportions was  Hypothesis testing or significance testing is a method for testing a claim or hypothesis about a parameter in a population, using data measured in a sample. Determine the appropriate test statistic and calculate it using the sample data. You conduct a study of men and find that ofmen tested,have red/green color blindness. Let subscript “1” reference the group of state employees, “2” the private sector employees. Null hypothesis. Based on the above information, do men have a higher Hypothesis Testing Is also called significance testing Tests a claim about a parameter using evidence (data in a sample The technique is introduced by considering a one-sample z test The procedure is broken into four steps Each element of the procedure must be understood inferential test, and assumptionsState the null and research hypothesesDetermine characteristics of the comparison distribution Whether this is the whole population or a control group, we need to find the mean and some measure of spread (variability) HYPOTHESIS TESTING (ONE SAMPLE)CHAPTERANOTHER APPROACH TO SUCH QUESTIONS hypothesis testing (almost always results in the same answer as  Question:Can the majority of people distinguish between expensive and inexpensive wine? In this method, we  I Hypothesis testing will rely extensively on the idea that, having a pdf, one can compute the probability of all the corresponding events.</p></translate>
