Assume the hourly wage rate for a fast-growing online job is normally distributes a mean of μ = $21.10. Suppose a random sample of n = 22 workers revealed a wage of = $20.00 and a standard deviation of s= $1.12. At a = 0.01, is there enough evidence to conclude that the mean hourly wage is than $21.10? a. Select the appropriate alternative hypothesis, H₁ or Ha: 0μ $20.00 Ομ < $20.00 ©μ > $20.00 O μ$21.10 © μ < $21.10 © μ > $21.10
