Victoria is doing a chi-square test to see if people in California have the same color preferences as people in Arizona. 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 Arizonans 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 state what Victoria should conclude about Californian’s and Arizonan’s color preferences? Let α = .05.

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

Males and Females responded to their happiness with their
supervisor (this is fictitious data).

You are doing a chi-square test with a 5 by 9 table of counts
(that is, 5 rows and 9 columns).
What is the degrees of freedom?
Suppose you get ?^2 = 45.23. Calculate the p-value.
Suppose that you want to see if there is association between
income level (high/medium/low) and gender.
a)Write the null hypothesis.
b)Use StatCrunch to calculate the test statistic (that is, the
x?2 value) and the p-value for this contingency table,
which shows the income level...
