For this study, why we would want to use Chi-Squared?
1.A study investigating the effects of second-hand smoke in working environments asked the following question: “How often do you experience second-hand smoke in a work environment/function? Never, Occasionally, Fairly Often, Very Often, Almost Always.” The question was asked of managers and employees to determine whether there was an association between position and the amount of second-hand smoke exposure.

Step 1
The chi-square test is generally used for testing relationship between categorical data.
For the described problem we have two categorical variables as, how often do you experience the second-hand smoke work environment (Never, Occasionally, Fairly Often, Very Often, Almost Always) and the position.
Step 2
Thus, to check the association between position and the amount of second-hand smoke exposure chi-squared test is best.
The best way to summarize the data is using the contingency table using appropriate number of rows and columns.

A seafood festival organizer is interested in whether there is a relationship between the number of ingredients in the clam chowders that are entered in the festival’s clam chowder contest and the ratings given to the chowders by the judges. The organizer requires each of the twelve restaurants in the competition to list all of its chowder's ingredients and requires each judge who tastes the clam chowders to rate each chowder from one through ten on a note card. The organizer then randomly selects twenty-five note cards. Assuming that all conditions for inference are met, which of the following significance tests should be used to investigate whether having more ingredients in the chowders is associated with a reduction in the ratings given to the chowders by the judges?
a. A chi-square test of independence
b. A two-sample t-test for a difference between means
c. A two-sample z-test for a difference between proportions
d. A linear regression t-test for slope
e. A matched pairs t-test for a mean difference

A political pollster selects a random sample of 75 registered voters from Allegheny County, Pennsylvania. The city of Pittsburgh is in Allegheny County. The pollster is interested in determining if the distribution of political party preference among registered voters in this county differs between those who live in Pittsburgh and those who live in the suburbs. The responses are displayed in the table.

 

The pollster would like to know if these data provide convincing evidence of a relationship between residential status and political party in the population of all registered voters in Allegheny County. The random and 10% conditions are met, and this table of expected counts shows that all expected counts are at least 5.

What is the value of the chi-square test statistic for this test?

χ‑2 = 2.64

χ‑2 = 2.83

χ‑2 = 6.95

χ‑2 = 8.03

We have studied 2 different test statistics, z, and X2. Explain the similarities in;
1. How each test statistic is calculated
2. How each test statistic is used to determine if the sample statistic provides enough evidence against the null hypothesis to reject it.
