b). level of significance : 0.10

c) z crit. = 2.576

d) z = 10.68 -10.33/ 2.7/sqrt(400).  = 2.592

e) Reject null hypothesis

f) reject  null hypothesis because z stat lies in critical region beyond z = 2.576

g) p ( z> 2.592). = 1- 0.9952 = 0.0048.  It means that there is throng evidence against Ho provided by sample data

h). The sample data provides the evidence that the mean hourly wage for private sector workers for their first job is greater than $ 10.33
