Use the dаtаset “vоter.sаv” frоm Canvas. This dataset is a simulated dataset that includes infоrmation about 30 voters. The variables include: voter education level (education), age, income, self-identification as liberal or conservative (libcon), political party (party), and the percentage of ballot issues they voted on in three elections (vote2012, vote2016, and vote2020). 7. Find the kurtosis of the income variable. Write out your calculations (i.e., the equation) in this text box. Round your final answer to 2 decimal places. Is there significant kurtosis? If so, what shape (platykurtic, mesokurtic, leptokurtic) is the graph? (2.5 pts) ***For this question, I am looking for the table with the kurtosis values in your output file. In the text box below, show your calculations for kurtosis, whether or not the kurtosis was significant, and the shape of the graph if there is significant kurtosis.***
This questiоn dоes nоt require а dаtа set. 9. Researchers are interested in validating a new drug for depression. Specifically, the researchers are interested in finding out if the new drug is more effective than the current industry standard drug. The efficacy of the drug is determined by scores on the Beck Depression Inventory (Beck et al., 1961). When taking the industry standard drug, patients' scores on the Beck Depression Inventory were lowered by 12 points on average. What would the researchers' null and alternative hypotheses be if they wanted to know whether depression scores are significantly lower when taking the new drug as opposed to the industry standard drug (which lowers BDI scores by an average of 12 points). List the null and alternative hypotheses for this research question. [I am looking for you to use the hypothesis notation we used in class] (5 pts) You can write mu for
