Question
  • Proportion of females in the relevant labor market: P(pop) = 51% (.51)
  • Proportion of females among hired: P(obs) = 6/37 = .16
  • N=24                My math is below:
  • z =  .16-.51/SR.51*((1-.51)/24)
  • .16-.51 = -.35
  • 1-.51 = .49
  • .49/24  = .020
  • .51*.020 = .0102
  • SR .0102 = .101
  • -.35/.101 = -3.47
  • Z = -1.42
