The melting points of two alloys employed in formulating solder were investigated by melting 21 samples of each material. The sample mean and standard deviation for alloy 1 was X1= 420.48 and S1= 2.34. And for alloy 2 they were X2= 425 and S2=32.5
Do the sample data support claim that both alloys have same variance of melting point ? employ alpha = 0.05 in reaching your conclusion
