In a recent survey conducted, a random sample of adults 18 years of age or older living in a certain country were asked their reaction to the word socialism.

(a) Does the evidence suggest individuals within each political affiliation react differently to the word "socialism"? Use the a = 0.05 level of significance.
State the hypotheses.
O A. Ho: OD = ED and OR = ER and O = E,
%3D
H1: At least one mean is different from what is expected.
O B. Ho: PD = PR = PI
H4: At least one of the proportions is different from the others.
O C. Ho: Political party and reaction are independent.
H1: Political party and reaction are dependent.
D. Ho: Political party and reaction are dependent.
H1: Political party and reaction are independent.
Compute the P-value.
The P-value is
|: (Round to three decimal places as needed.)
