The article "Gypsum Effect on the Aggregate Size and Geometry of Three Sodic SoilsUnder Reclamation" (I. Lebron, D. Suarez, and T. Yoshida, Journal of the Soil ScienceSociety of America, 2002:92-98) reports on an experiment in which gypsum was added invarious amounts to soil samples before leaching. One of the outcomes of interest was thepH of the soil. Gypsum was added in four different amounts. Three soil samples receivedeach amount added. The pH measurements of the samples are presented in the followingtable.Gypsum (g/kg)pH0.007.887.727.680.117.817.647.850.197.847.637.870.387.807.738.00Can you conclude that the pH differs with the amount of gypsum added? Provide the valueof the test statistic and the P-value.

The results of the t-test for zinnia height: p=0.381. Did these zinnia height results support the alternative hypothesis of this study? Yes, the zinnia were taller in the mycorrhizae soit No, there was no statistical difference in zinnia heights between the soils.

The decline of salmon fisheries along the Columbia River in Oregon has caused great concern among commercial and recreational fishermen. The paper 'Feeding of Predaceous Fishes on Out-Migrating Juvenile Salmonids in John Day Reservoir, Columbia River' (Trans. Amer. Fisheries Soc. (1991: 405-420) gave the accompanying data on y = maximum size of salmonids consumed by a northern squaw fish (the most abundant salmonid predator) and x = squawfish length, both in mm. Here is the computer software printout of the summary: Coefficients: Estimate Std.

Skoog.151.7-22. Two different analytical methods were used to determine residual chlorine in sewage effluents. Both methods were used on the same samples, but each sample came from various locations with differing amounts of contact time with the effluent. Two methods were used to determine the concentration of Cl in mg/L, and the results are shown in the following table: Sample Method A Method B 1 0.39 0.36 0.84 1.35 3 1.76 2.56 4 3.35 3.92 4.69 5.35 7.70 8.33 7 10.52 10.70 8. 10.92 10.91 (a) What type of t test should be used to compare the two methods and why? (b) Do the two methods give different results? State and test the appropriate hypotheses. (c) Does the conclusion depend on whether the 90%, 95%, or 99% confidence levels are used?
