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

For each of the following examples, state whether the chi-square
goodness-of-fit test or the chi-square test for independence is
appropriate, and state the degrees of freedom (df) for the
test.
Part A) An instructor tests whether class attendance (low, high)
and grade point average (low, average, high) are independent.
- State whether the chi-square goodness-of-fit test or the
chi-square test for independence is appropriate.
- State the degrees of freedom for the test. df =
Part B) A student tests...

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...

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

How can I do a chi square hypothesis test whether the
provided data follows f-distribution?
I need to know how to set up the hypothesis test and how to check
if the data follows f-distribution.

Janna is doing a chi-square test to see if people in California
have the same color preferences as people in Nevada. A sample of
100 Californians were polled. Thirty-five people prefer yellow,
fifty people prefer green, and fifteen people prefer red. A sample
of 50 people from Nevada were polled. Ten people prefer yellow, ten
people prefer green, and thirty people prefer red. Calculate the
test statistic. State the critical value. Come to a conclusion
about the null hypothesis. And...
