Question
A melting point test of n = 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 o = 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: μ = 155 versus H₁ :μ ‡ 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 ß-error if the true mean is μ = 150? Assume that a = 0.01. i (d) What value of n would be required if we want ß < 0.15 when μ = 150? Assume that a = 0.01. i
