  5. 5. Out of 500 workers in a factory the mean wages and standard deviation are 500 and 48 respectively. What is the probability that a worker selected at random is having wages more than 600? P (X >600) • • Or 1 – P (X< = 600) • 1 – p(X -500/48 < = 600-500/48) • Or 1 – p(2.08) or 1-.9624 =.0376 www.afterschoool.tk AFTERSCHO☺OL's MATERIAL FOR PGPSE PARTICIPANTS
