A melting point test of n = 10 samples of a binder used on the melting point is normally distributed with a = 1.5 F. For (b) and (c), round your answers to 4 decimal places (e.g. 98.7654). For (d). give an integer answer. (a) Test Ho: #= 155 versus H₁:# # 155 using a = 0.01. Ho (b) What is the P-value for this test? Use a z-score with two decimal places. i (c) What is the B-error if the true mean is μ = 150? Assume that a = 0.01. (d) What value of n would be required if we want < 0.1 when μ = 150? Assume that a = 0.005.

Question
A melting point test of = 10 samples of a binder used on manufacturing a rocket propellant resulted in x = 154.2 F. Assume that the melting point is normally distributed with a = 1.5 "F. For (b) and (c), round your answers to 4 decimal places (e.g. 98.7654). For (d), give an integer answer. (a) Test Ho: H = 155 versus H₁ 155 using a = 0.01. Ho (b) What is the P-value for this test? Use a z-score with two decimal places. i (c) What is the B-error if the true mean is = 150? Assume that a = 0.01. (d) What value of n would be required if we want < 0.1 when = 150? Assume that a = 0.005.
