Gini Index: The Gini Index is a measure of how evenly income is distributed within a country, ranging from 0 to 100. An index of 0 suggests income is distributed with perfect equality. The higher the number, the worse the income inequality. The data below represents the Gini index for a random sample of countries. Examine the sample's kurtosis for normality for α=0.05. (40 points) State the null and alternative hypotheses. Obtain kurtosis and the standard error of kurtosis. Obtain z-score. State the decision rule. Report your findings.
