Exercise 7. Lebron James' height

In the previous exerceise we estimated the proportion of seven footers in the NBA using this simple code:

p <- 1 - pnorm(7*12, 69, 3)
N <- round(p * 10^9)
10/N

Repeat the calculations performed in the previous question for Lebron James' height: 6 feet 8 inches. There are about 150 players, instead of 10, that are at least that tall in the NBA.

Report the estimated proportion of people at least Lebron's height that are in the NBA.
