A melting point test of = 10 samples of a binder used on manufacturing a rocket propellant resulted in x = 154.2 F. Assume thatthe 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 H₁155 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.

Q2. A laundry for car wash found that the average, for small size car, cleaning time is 5 mins in the morning and 6.5 mins at evening time when a sample of size 30 is taken at the two time periods. From the previous record, the laundry manager knew that car oj = 2 mins for the morning shift and oz = 2.5 mins for morning and evening repectively. Find the interval estimate for 4 - 42 with 90% confidence level.
