4. Using the same data provided to you, divide your dependent variable 2 (variable in the firstcolumn) samples using the midpoint of the data points as a division point. For example, if yourdependent variable has 40 data points, then points 1 to 20 become sample 1 and 21 to 40 becomes sample 2. Using any tables or graphs, compare and highlight the differences between the two samples, mentioning any interesting aspects of the two samples. [4]5. Perform any relevant tests to determine whether there is any difference between the means of the two population groups from which these two samples were extracted. Make sure to state and test any underlying assumptions first. [6]6. For any test you conduct, clearly state your hypotheses, test statistic, critical value andconclusion (Do not just state "accept" or "reject", provide a meaningful conclusion).7. Present all the results and give a brief write up in a report of no more than 2 pages (doublespacing).
