Skewness and kurtosis should not be tested when using the chi-square test of independence.
True or False
The major difference between the Mann-Whitney U-test and the Kruskal-Wallis H test is the number of independent variables.
True or False
Homework Answers
1)Skewness and kurtosis should not be tested when using the chi-square test of independence.
True : (Since chi square test does not require normality condition to be true)
2)
True : Mann-Whitney U-test can be run on 2 independent variables while Kruskal-Wallis on more than 2 ndependent variables

Perform a chi-square independence test using the critical value approach, provided the conditions for using the test are met. Be sure to state the hypotheses and the significance level, to obtain the expected frequencies, to obtain the critical value, to compute the value of the test statistic, and to state your conclusion. 160 students who were majoring in either math or English were asked a test question, and the researcher recorded whether they answered the question correctly. The sample results...
