Chapter 10.1, Problem 7E

An experiment was carried out to compare electrical resistivity for six different low-permeability concrete bridge deck mixtures. There were 26 measurements on concrete cylinders for each mixture; these were obtained 28 days after casting. The entries in the accompanying ANOVA table are based on information in the article “In-Place Resistivity of Bridge Deck Concrete Mixtures” (ACI Materials J., 2009: 114–122). Fill in the remaining entries and test appropriate hypotheses.

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. Determine the test statistic t=?
The yield of alfalfa from a random sample of six test plots is 1.4, 1.6, 0.9, 1.9, 2.2,and 1.2 tons per acre. Assume the data can be looked upon as a sample from anormal population. Test at the 0.05 level of significance whether this supports thecontention that the average yield for this kind of alfalfa is 1.5 tones per acre.
The authors of the paper "Statistical Methods for Assessing Agreement Between Two Methods of Clinical Measurement" compared two different instruments for measuring a subject's ability to breathe out air.† (This measurement is helpful in diagnosing various lung disorders.) The two instruments considered were a Wright peak flow meter and a mini-Wright peak flow meter. Seventeen subjects participated in the study, and for each subject air flow was measured once using the Wright meter and once using the mini-Wright meter.
