Five samples of a ferrous-type substance were used to determine
if there is a difference between a laboratory chemical analysis and
an X-ray fluorescence analysis of the iron content. Each sample
was split into two subsamples and the two types of analysis were
applied, with the accompanying results. Assuming that the
populations are normal, test at the 0.05 level of significance
whether the two methods of analysis give, on the average, the
same result.
Sample X-ray Chemical
1, 2.1, 2.2
2, 1.9, 1.7
3, 2.3, 2.6
4, 2.1, 2.4
5, 2.4, 2.4
Let sample 1 be the X-ray fluorescence results and let sample 2 be the laboratory chemical results. State the null and alternative hypotheses Ho HD = 10 H:HD 10 Determine the test statistic. (Round to two decimal places as needed.) State the proper conclusion V Ho. There evidence to conclude that the two types of analysis give
