Explanation / Answer

Football player
P(X<190)=P(z<(190-220)/30)=P(z<-1) = 0.1587
Around 16% of football players weigh less than Pierre.

Ramone Test
z = (29 - 24)/2 = 2.5
P(z>2.5) = 0.0062
He is among the top 10 percent

Reading Score
z = (190 - 175)/18 = 0.8333
P(z>0.8333) = 0.2023
This means Janie will not be put into advanced class.

Body weight
Michell is very heavy relative to other members of his population
