1. A melting point test with 10 samples of a binder used in manufacturing a rocket propellant resulted in average melting point of 165.8F.The population standard deviation is known and is equal to 7.9F. Assume that the melting point is normally distributed.

Test Ho:= 160 versus Ha:160.Find the pvalue for this test.How do the results differ for =0.05 and =0.01?

Make concluding statements in both cases.
