Answer #1

Let X denotes the height of a randomly selected man.

X ~ Normal(170, 6.52)

a) The probability of randomly selecting a man that is exactly 170 cm tall

since X is a coninuous random variable

b) The percent of the male population of Thailand is between 165 cm to 175 cm tall

c) The percent of the male population of Thailand is over 175 cm tall

d) The percent of the male population of Thailand is below 160 cm tall
