Question: LetXbe a random variable that represents the weights in pounds (lb) of adult males who are in their 40s.X has a normal distribution with mean=166

LetXbe a random variable that represents the weights in pounds (lb) of adult males who are in their 40s.X

has a normal distribution with mean=166 lbs and standard deviation=6 lbs. An adult male in his 40s that weighs above 169.6 is considered overweight.

A) What is the probability that one adult male in his 40s is overweight? (Round your answer to four decimal places.)

B) What is the probability that 17 adult males in their 40s have a mean weight over 169.6 lbs? (Round x

to two decimal places and your answer to four decimal places.)

C) What is the probability that 31 adult males in their 40s have a mean weight over 169.6 lbs? (Round

xto two decimal places and your answer to four decimal places.)
