The mean is 15.42 with a standard deviation of 0.16. Assume the number of parts produced is approximately normal.
-The null and alternative hypotheses to test whether the number of parts produced by the overhauled system differs from 15.5 is _____.

• A)H₀: ? = 15.5 vs.H_a: ? ? 15.5
• B)H₀: ? ? 15.5 vs.H_a: ? < 15.5
• C)H₀: ? ? 15.42 vs.H_a: ? < 15.42
• D)H₀: ? ? 15.5 vs.H_a: ? = 15.5
• E)H₀: ? ? 15.5 vs.H_a: ? > 15.5
