Chi-Square Test for Independence
Using Chi-Square, we are looking to see if there is a
significant difference between what we would expect results to be,
and what the actual results were. That is, expected vs.
observed. Use alpha = .05

What is the critical value for a chi-square test with 13 degrees
of freedom at the 1 percent level of significance? If the
chi-square test statistic were 16.98, what would you conclude
regarding the null hypothesis? What would you conclude if the
chi-square value were 68.03? (30 points)
Choose either the Chi Square Goodness of Fit test OR the Chi
Square Test for Independence. Give an example of a research
scenario that would use this test, including your hypothesis AND
what makes the test suitable for your variables chosen
For
the purpose of using the chi-square test for inter-arrival data
fitting against exponential distribution (goodness-of-fit) for
which the class intervals are not given, the analyst must determine
the class interval endpoints. Assume that based on the collected
data, the average inter-arrival time is 14.62 minutes. Assume that
number of class intervals to be used for data classification is
equal to 5. Calculate the endpoint of the first interval, Le. at
knowing that a0-0 and that the data are in...
1) What’s the difference among the chi-square test for goodness
of fit, the chi-square test for independence, and the chi-square
test for homogeneity
2) State the requirements to perform a chi-square test
