Hypothesis Testing. Follow the description of the assignmentbelow.
Think of a problem of your interest, set up H0 and Ha andconduct the hypothesis test.
Describe the research problem. Determine the level ofsignificance – use the levels: α=0.1 ,α=0.05 or α=0.01.
Identify the target population and the population parameter ofinterest (μ or p; μ_1- μ_2 or p_1-p_2). Set up H0 and Ha.
Provide sample evidence: (1) Data source: a) primary sourcesi.e. survey, experiment, observation or b) secondary sources i.e.database/registry, census, internet portals etc.; (2) Sampleproperties: random, large or small sample; and (3) Sample data:sample size, sample mean(s) or sample proportion(s).
Define critical test statistic values (z or t-value). Calculatesample test-statistics and observed significance level(p-value).
Evaluate the sample evidence: (1) compare the critical valuesfor rejection with sample statistics values and (2) compareobserved significance level (p-value) with significance level(α).
Provide conclusion (whether you reject or do not reject H0) andinterpret the results.
