The hypothesis being tested is:

H0: p1 = p2 = p3 = p4

Ha: There are voters’ preferences for the different political parties in Europe

observed expected O - E (O - E)² / E
29 26.250 2.750 0.288
32 26.250 5.750 1.260
19 26.250 -7.250 2.002
25 26.250 -1.250 0.060
105 105.000 0.000 3.610
3.61 chi-square
3 df
