A random sample of 22 Zappos employees was found to have an average age of 33.9 years. The standard deviation for this sample was 4.1 years. Amazon would like to set a = 0.025. The correct hypothesis statement for this hypothesis test would be a. b. Ο c. HO: μ = 36; Hl: p < 36. d. H0: us 36; H1: μ> 36. H0: μ = 36; H1: μ + 36. H0: p= 33.9; H1: μ = 33.9. O
