Detailed explanation coming soon!
//Looking at Z table: http://www.sjsu.edu/faculty/gerstman/EpiInfo/z-table.htm
public class Solution {
public static void main(String[] args){
//MEAN = 70
//SD = 10
// P(X > 80)
//= 1 - P(X < 80)
//= 1 - P(Z < (80-70)/10)
//= 1 - P(Z < 1)
//= 1 - 0.8413
//= 0.1587
System.out.println("15.87");
// P(X > 60)
//= 1 - P(X < 60)
//= 1 - P(Z < (60-70)/10)
//= 1 - P(Z < -1)
//= 1 - (1 - Z(1))
//= Z(1)
//= 0.8413
System.out.println("84.13");
//**Note 60 is the same distance away from the mean as 80
System.out.println("15.87");
}
