Question 1
A survey of Ohio University students was conducted to determine if there was a particular Green that was desired by
students to live on. A sample of students responses are reproduced below. Do students prefer a particular Green?
Use critical value = 5.99.
Use the numbers below for this question only!
West Green South Green East Green
38 80 108
What would the expected value for the West Green be?
18.5
75.33 ± 0.2
Response
Feedback:
This problem requires using a chi-square goodness-of-fit test. The formulas for the expected values
(or expected frequencies) and the chi-square value are on pages 1-3 of the module 6 course notes.
Also see Howell Section 19.1.
Question 2
A survey of Ohio University students was conducted to determine if there was a particular Green that was desired by
students to live on. A sample of students responses are reproduced below. Do students prefer a particular Green?
Use critical value = 5.99.
Use the numbers below for this question only!
West Green South Green East Green
34 60 94
What is the calculated chi-squared value?
28.89 ± 0.2
Question 3
Using a critical value of 5.99, was there a significant preference for where students live based on the obtained chi-
square value in Question 2?
Yes
No
Question 4
A local sports bar wanted to determine whether Ohio University students prefer a particular type of food in their
establishment. A sample of students responses are reproduced below. Do students prefer a particular type of bar

food? Use critical value = 6.58.

What is the calculated chi-squared value?
0.12 ± 0.02
Question 6
Using a critical value of 6.58, was there a significant preference for what students eat in a sports bar based on the
obtained chi-square value in Question 5?
Yes
No
Question 7
In a study of binge drinking among undergraduates at Ohio University, a researcher was interested in gender
differences as related to binge drinking and to drinking-related arrests. She wanted to know two things: (a) Is there a
significant relationship between gender and binge drinking (as defined by 5 or more drinks at one sitting), and (b) Is
there a significant relationship between gender and drinking-related arrests? A random sample of males and females
were asked about their experiences with binge drinking and with drinking-related arrests.
