Please solve part d and e only. 

The body mass index (BMI) of a person is defined to be the person’s body mass

divided by the square of the person’s height. The article “Influences of Parameter

Uncertainties within the ICRP 66 Respiratory Tract Model: Particle Deposition” (W.

Bolch, E. Farfan, et al., Health Physics, 2001:378–394) states that body mass index (in

kg/m2) in men aged 25–34 is lognormally distributed with parameters μ = 3.215 and σ = 0.157.

a.Find the mean and standard deviation BMI for men aged 25–34. 

b.Find the standard deviation of BMI for men aged 25–34.

c.Find the median BMI for men aged 25–34.

d.What proportion of men aged 25–34 have a BMI less than 20?

e.Find the 80th percentile of BMI for men aged 25–34.
