a) The table shows 27+21 = 48 people with high cholesterol. Of those, 21 are women, so the relative frequence is 21/48 = 0.4375 ≈ 0.44

b) This question is ambiguous. If we assume it is asking the relative frequency of normal cholesterol among people who are men, that is 23 men out of 27+23 = 50 men surveyed. The relative frequency is 23/50 = 0.46
