A melting point test of n = 10 samples of a binder used in manufacturing a rocket propellant resulted in xbar = 154.2°F. Assume that the melting point is normally distributed with σ =1.5°F.
What is the p value for this test?
Incorrect
What is the β error if the true mean is μ = 150?
Incorrect
What value of n would be required if we want β < 0.1 when μ = 150? Assume that α = 0.01.
