Assume that average annual salary for a worker in th u.s. is $39,000 and the
 annual annual salary for americans are normally distributed with a SD = $7,000
 P(X<25) = P(z < -2)  NORMSDIST (-2) = .0228,   2.28%
P(X >44) = 1- P(z < (44,000 - 39,000)/7000) = 1 - P(z< .7143) = 1- .7325 = .2375,  {{{highlight(23.75)}}}%
