The melting points of two alloys used in formulating solder were investigated by melting 21 samples of each material. The sample mean and standard deviation for alloy 1 was x1 = 420oF and s1 = 4oF, while for alloy 2 they were x2 = 426oF, and s2 = 3oF. Do the sample data support the claim that both alloys have the same melting point? Use a = 0.05 and assume that both populations are normally distributed and have the same standard deviation. Find the P-value for the test.
