Current Attempt in Progress

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 = 1.5 F.

For (b) and (c), round your answers to 4 decimal

places (eg. 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.

(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=0.02.
