A melting point test of n = 10 samples of a binder used in manufacturing a rocket propellant resulted in Assume that melting point is normally distributed with .
(a) Test H0: μ = 155 versus H0: μ  155 using a = 0.01.
(b) What is the P-value for this test?
(c) What is the B-error if the true mean is μ = 150?
(d) What value of n would be required if we want B < 0.1 when μ = 150? Assume that a = 0.01.
