Answer the following questions:
1. What is our null hypothesis?
a. The observed frequency is different from the expected frequency, meaning that there is a difference in political affiliation among Buffalo State
students in PSY306 and the general population.
b. The observed frequency is different from the expected frequency, meaning that there is not a difference in political affiliation among Buffalo
State students in PSY306 and the general population.
c. The observed frequency is not different from the expected frequency, meaning that there is not a difference in political affiliation among
Buffalo State students in PSY306 and the general population.
d. The observed frequency is not different from the expected frequency, meaning that there is a difference in political affiliation among Buffalo
State students in PSY306 and the general population.
2. What is the alternative hypothesis
a. The observed frequency is different from the expected frequency, meaning that there is a difference in political affiliation among Buffalo State
students in PSY306 and the general population.
