a) 15.58

b) 39.06

Step-by-step explanation:

MENSA is organization whose member have IQs in the top 2% of the population. IQs are normally distributed with mean 100, and the minimum IQ score required for admission to MENSA is 132.

From standard normal table z value for top 2% = 2.054

132 = 100+2.054*σ

σ = (132-100) / 2.054=15.58

(b) Cholesterol levels for women aged 20 to 34 follow an approximately normal distribution with mean 185 milligrams per deciliter (mg/dl). Women with cholesterol levels above 220 mg/dl are considered to have high cholesterol and about 18.5% of women fall into this category.

From standard normal table z value for top 18.5% = 0.896

220 = 185+0.896*σ

σ = (220-185) / 0.896 = 39.06
