Group assignment III: Hypothesis Testing Please form up to three person groups (individual work is also possible but not recommended) and follow the description of the assignment below. Think of a problem of your (group) interest, set up HO and Ha and conduct the hypothesis test . Describe the research problem. Determine the level of significance - use the levels: a-0.1 ,a=0.05 or a=0.01. . Identify the target population and the population parameter of interest (u or p; u_1- u_2 or p_1-p_2). Set up HO and Ha. . Provide sample evidence: (1) Data source: a) primary sources i.e. survey, experiment, observation or b) secondary sources i.e. database/registry, census, internet portals etc.; (2) Sample properties: 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). Calculate sample test-statistics and observed significance level (p-value). Evaluate the sample evidence: (1) compare the critical values for rejection with sample statistics values and (2) compare observed significance level (p-value) with significance level (a). Provide conclusion (whether you reject or do not reject HO) and interpret the results. The assignments are subject to teacher assessment. Good projects... ... are based on an original and meaningful research problem, and on representative and interesting sample evidence; ...present a correctly conducted hypothesis testing procedure with a valid conclusion and well interpreted results; ...are clear, and have a nice presentation (include images if relevant). Be creative and have fun
