The article " The Ball-on-Three-Ball Test for Tensile Strength: Refined Methodology andResults for Three Hohokam Ceramic Types" (M. Beck, American Antiquity, 2002:558-569)discusses the strength of ancient ceramics. Several specimens of each of three types ofceramic were tested. The loads (in kg) required to caack the specimens are as follows:CeramicLoads (kg)TypeSacaton 15, 30, 51, 20, 17, 19, 20, 32, 17, 15, 23, 19, 15, 18,16, 22, 29, 15, 13, 1527, 18, 28, 25, 55, 21, 18, 34, 23, 30, 20, 30, 31, 25,28, 26, 17, 19, 16, 24, 19, 9, 31, 19, 27, 20, 43, 1520, 16, 20, 36, 27, 35, 66, 15, 18, 24, 21, 30, 20, 24,GilaPlainCasaGrande 23, 21, 13, 21Construct comparative boxplots for the three samples.b.

A real estate broker recently took a sample of recently sold homes by her agents. The square footage of the 10 homes was as follows: a) 2420 1750 3200 2785 2800 1800 1950 2100 2005 2000 b) Is there evidence that the average home sold was greater than 2000 square feet?

Using all 1991 birth records in the computerized national birth certificate registry compiled by the National Center for Health Statistics (NCHS), statisticians Traci Clemons and Marcello Pagano found that the birth weights of babies in the United States are not symmetric ("Are babies normal?" The American Statistician, Nov 1999, 53:4). However, they also found that when infants born outside of the "typical" 37-43 weeks and infants born to mothers with a history of diabetes are excluded, the birth weights of the remaining infants do follow a Normal model with mean u = 3432 g and standard deviation o = 482 g. The following questions refer to infants born from 37 to 43 weeks whose mothers did not have a history of diabetes. Compute the z-score of an infant who weighs 4769 g.

The article "Gypsum Effect on the Aggregate Size and Geometry of Three Sodic Soils Under Reclamation" (I. Lebron, D. Suarez, and T. Yoshida, Journal of the Soil Science Society of America, 2002:92-98) reports on an experiment in which gypsum was added in various amounts to soil samples before leaching. One of the outcomes of interest was the pH of the soil. Gypsum was added in four different amounts. Three soil samples received each amount added. The pH measurements of the samples are presented in the following table. Gypsum (g/kg) pH 0.00 7.88 7.72 7.68 0.11 7.81 7.64 7.85 0.19 7.84 7.63 7.87 0.38 7.80 7.73 8.00 Can you conclude that the pH differs with the amount of gypsum added? Provide the value of the test statistic and the P-value.

The article "Effect of Granular Subbase Thickness on Airfield Pavement Structural Response" (K. Gopalakrishnan and M. Thompson, Journal of Materials in Civil Engineering, 2008:331-342) presents a study of the effect of the subbase thickness (in mm) on the amount of surface deflection caused by aircraft landing on an airport runway. Two landing gears, one simulating a Boeing 747 aircraft, and the other a Boeing 777 aircraft, were trafficked across four test sections of runway. The results are presented in the following table. Section 3 4 Boeing 747 Boeing 777 4.01 3.87 3.72 3.76 4.57 4.48 4.36 4.43 Can you conclude that the mean deflection is greater for the Boeing 777?
