Fivesamples of ferrous type substance are to be used to determine if there is a difference between a laboratory chemical analysis and an X ray fluorescence analysis of the iron content. The below table are samples from each process that show the iron content analysis. Test the hypothesis that the variances of both ferrous type (X- Ray and Chemical) iron content are equivalent (Null hypothesis; Ho, variances are equal) against the alternate that the variances are not equal (Ha: variances not equal). Conduct the test at alpha equal .1 level of significance. Answer the following questions What is the Critical F value? What is the final decision based on the analysis?

X Ray	Chemical
2.0	2.2
2.0	1.9
2.3	2.5
2.1	2.3
2.4	2.4
