An Investigation of the CaCO3-CaF2-K2SiO3- SiO2-Fe flux system usingthe Submerged Arc Welding Process on HSLA-100 and AISI-1081 Steelswas conducted in a series of experiments. In this investigation, the weldingfluxes with differing chemical compositions were prepared. Several weldsusing each flux were made on AISI-1018 steel base metal. The ANOVAresults of hardness measurements (in Brinell scale) of five welds using eachof four fluxes are presented in Table 2.Table 2: ANOVA of hardness measurementsSource of df Sum of squaresMean ofvariation(SS)FluxErrorTotal316191023.6608.3squares(MS)(1) Complete the ANOVA table in Table Q2(a)Fo(ii) By using a = 0.05, can we conclude that the flux types have significantinfluence on the Brinell hardness?

An experiment is designed to determine the effect of four different types of tips in a hardness tester on the observed hardness of a metal alloy. Four specimens of the alloy were obtained, and each tip was tested once on each specimen, producing the following data: Specimen Туре of Tip 4 9,3 9,4 9,2 9,7 9,4 9,6 9,8 9,5 10 9,3 9,4 9,6 9,9 9,7 10,2 3 4 10 What is your conclusion about this test at 0.05 level of significance? a. There is no difference between four specimens of the alloy. O b. At least one specimens of the alloy is different.

Seedlings of understory trees in mature tropical rainforests must survive and grow using inter- mittent flecks of sunlight. How does the length of exposure to these flecks of sunlight (fleck duration) affect growth? Leakey et al. (2005) experimentally irradiated seedlings of the Southeast Asian rainforest tree Shorea leprosula with flecks of light of varying duration while maintaining the same total irradiance to all the seedlings. Their data for 21 seedlings are listed in the following table. i. What is the rate of change in relative growth rate per minute of fleck duration? provide a standard error for your estimate. ii. using these data, test the hypothesis that fleck duration affects seedling growth rate. iii. Calculate a 99% confidence interval for the slope of the population regression.

Poly(3-hydroxybutyrate) (PHB), a semicrystalline polymer that is fully biodegradable and biocompatible, is obtained from renewable resources. From a sustainability perspective, PHB offers many attractive properties though it is more expensive to produce than standard plastics. The accompanying data on melting point (°C) for each of 12 specimensof the polymer using a differential scanning calorimeter appeared in the article “The Melting Behaviour of Poly (3-Hydroxybutyrate) by DSC. Reproducibility Study” (Polymer Testing, 2013: 215-220). Compute the following:a. The sample rangeb. The sample variance s2 from the definition [Hint: First subtract 180 from each observation.]c. The sample standard deviationd. s2 using the shortcut method
The article "Oxidation State and Activities of Chromium Oxides in Cao-SiO,-CrO, Slag System" (Y. Xiao, L. Holappa, and M. Reuter, Metallurgical and Materials Transactions B, 2002:595-603) presents the amount x (in mole percent) and activity coefficient y of CrO,5 for several specimens. The data, extracted from a larger table, are presented in the following table. х У 2.6 10.20 5.03 19.9 8.84 0.8 6.62 5.3 2.89 20.3 2.31 39.4 7.13 5.8 3.40 29.4 5.57 2.2 7.23 5.5 2.12 33.1 1.67 44.2 5.33 13.1 16.70 0.6 9.75 2.2 2.74 16.9 2.58 35.5 1.50 48.0 Compute the least-squares line for predicting y from x. b.

3. An experiment is conducted to measure the flex (amount of bending) in a thin composite beam when placed under a known load (force). Smaller beams made of the same material will then be used as springs to protect electronics. The manufacturer needs the beam to flex on average 5.0 mm, with 95 % of all samples having a flex between 4.7 mm and 5.3 mm. After testing the flex of 20 samples, the following numbers are found: (d) (e) 20 (f) (g) i=1 Each sample has the flex measured to the nearest 0.1 mm using electronic calipers. (a) What is the mean flex found using 20 samples? What is the sample standard deviation of flex four using 20 samples? What is the 95% confidence interval for an individual sample? (Not true mean this time!) That is, in what range would we expect the flex of 95 % of the samples to be found? x₁ = 102.2 mm 20 Σχι" = 523.7 mm2 Xi i=1 Does the set of samples used satisfy the desired failure rate? Explain the reasoning behind your answer. What percent difference is there…
