Question:

Determine in the following whether type I, type II, or no error occurs
a) H₀ ∶ μ ≤ 12 is not rejected. True population mean is 15.
b) H₀ ∶ μ ≥ 27 is rejected. True population mean is 35.
c) H₀ ∶ μ ≤ 90 is not rejected. True population mean is 90.
d) H₀ ∶ μ ≥ 75 is rejected. True population mean is 80.
