5.39 Deep mixing of soil. Deep mixing is a ground improvementmethod developed for soft soils like clay, silt, and peat.Swedish civil engineers investigated the properties of soilimproved by deep mixing with lime-cement columns in thejournal Giorisk (Vol. 7, 2013). The mixed soil was testedby advancing a cylindrical rod with a cone tip down intothe soil. During penetration, the cone penetrometer mea-sures the cone tip resistance (megapascals, MPa). The re-searchers established that tip resistance for the deep mixedsoil followed a normal distribution with μ = 2.2 MPa andσ = .9 MPa.a. Find the probability that the tip resistance will fallbetween 1.3 and 4.0 MPa.b. Find the probability that the tip resistance will exceed1.0 MPa.c. Find a value of tip resistance, T, such that 35% of all soilsamples have tip resistance values that exceed T.

Recently there has been increased use of stainless steel claddings in industrial settings. Claddings are used to finish the exterior walls of a building and help weatherproof the structure. To ensure the quality of claddings, it is essential to know how welding parameters impact the cladding process. The authors of “Mathematical Modeling of Weld Bead Geometry, Quality, and Productivity for Stainless Steel Claddings Deposited by FCAW” (J. Mater. Engr. Perform., 2012: 1862–1872) in vestigated how y 5 deposition rate was influenced by x1 = feed rate (Wf , in m/min) and x2 = welding speed (S, in cm/min).

LEDs and CFLs. Light-emitting diodes (LEDs) and compact fluorescent lights (CFLs) are lightbulbs that are supposed to last up to fifty times longer than old fashioned incandescent lightbulbs and also use less energy. Consumer Reports sampled eighteen different 60-watt LED and CFL lightbulbs. The following table lists their brightness, in lumens. Use the technology of your choice to decide whether applying the z-interval procedure to these data is reasonable.

The depth of wetting of a soil is the depth to which water content will increase owing to extemal factors. The article "Discussion of Method for Evaluation of Depth of Wetting in Residential Areas" (J. Nelson, K. Chao, and D. Overton, Journal of Geotechnical and Geoenvironmental Engineering, 2011:293-296) discusses the relationship between depth of wetting beneath a structure and the age of the structure. The article presents measurements of depth of wetting, in meters, and the ages, in years, of 21 houses, as shown in the following table. Age Depth 7.6 4 4.6 6.1 9.1 3 4.3 7.3 5.2 10.4 15.5 5.8 10.7 4 5.5 6.1 10.7 10.4 4.6 7.0 6.1 14 16.8 10 9.1 8.8 Compute the least-squares line for predicting depth of wetting (y) from age (x). b.

Twinned drill holes. A traditional method of verifying mineralization grades in mining is to drill twinned holes, i.e., the drilling of a new hole, or “twin," next to an ear- lier drill hole. The use of twinned drill holes was investi- gated in Exploration and Mining Geology (Vol. 18, 2009). Geologists use data collected at both holes to estimate the total amount of heavy minerals (THM) present at the drilling site. The data in the following table (based on information provided in the journal article) represent THM percentages for a sample of 15 twinned holes drilled at a diamond mine in Africa. The geologists want to know if there is any evidence of a difference in the true THM means of all original holes and their twin holes drilled at the mine. a. Explain why the data should be analyzed as paired differences. b. Compute the difference between the “Ist Hole" and "2nd Hole" measurements for each drilling location. c. Find the mean and standard deviation of the differ- ences, part b.

Concrete admixtures are natural or manufactured chemicals added during concrete mixing to enhance specific properties of the fresh or hardened concrete, such as workability, durability, or early and final strength. Two admixtures are being tested to determine how they affect the strength of the concrete. Both admixtures are in use but admixture 2 is cheaper and it should be adopted provided that it does not affect the compressive strength of the concrete. A test was conducted in the laboratory and the results are shown in the table. Assume that the strengths are normally distributed with the same standard deviation.

A study was conducted by the Department of Biological Sciences at Virginia Tech to determine if there is a significant difference in the density of organisms at two different stations located on Cedar Run, a secondary stream in the Roanoke River drainage basin. Sewage from a sewage treatment plant and overflow from the Federal Mogul Corporation settling pond enter the stream near its headwaters. The accompanying data give the density measurements, in number of organisms per square meter, at the two collecting stations. Can it be concluded, at the 0.05 level of significance, that the average densities at the two stations are equal? Assume that the observations come from normal populations with different variances. Click the icon to view the data on organisms per square meter. Let sample 1 be the station 1 data and let sample 2 be the station 2 data. State the null and alternative hypotheses.
