Explanation / Answer

a)

sample size = 181

b) Find Expected Frequencies:

Ei = (Row total) * (Column total) / sample size

E1 = (82) * (45) / 181

E1 = 20.39

E2 = (82) * (33) / 181

E2 = 14.95

E3 = (82) * (57) / 181

E3 = 25.82

E4 = (82) * (46) / 181

E4 = 20.84

E5 = (99) * (45) / 181

E5 = 24.61

E6 = (99) * (33) / 181

E6 = 18.05

E7 = (99) * (57) / 181

E7 = 31.18

E8 = (99) * (46) / 181

E8 = 25.16

Expected Frequency Table:
