14.1.2A two-factor experiment is conducted to investigate how the tensile strength of a graphite-epoxycomposite depends upon the formulation of the composite and the temperature of the composite.Four different composite formulations are considered in the experiment and they are taken to befactor A. Three different temperature levels are considered (low= 1, medium = 2, and high = 3) andthey are taken to be factor B. The response variable is tensile strength and it is measured for twodifferent samples at each experimental configuration. The sums of squares SSA = 160.61, SSB = 580.52,SSAB = 58.01, and SSE = 66.71 are obtained. The cell sample averages are X₁1 = 27.05, X12. = 18.80, X13- =16.40, X21. = 25.50, X22- 15.60, X23. = 8.25, X31- = 24.15, X32. = 17.90, X33 = 16.95, X1 = 30.00, X42. = 23.40,and X43. = 17.65.(a) Construct the analysis of variance table.(b) Show that there is no evidence of an interaction effect but that there are main effects for bothfactors.(c) Construct pairwise confidence intervals to compare the four different graphite-epoxy compositeformulations. What conclusions can you draw?(d) Construct pairwise confidence intervals to compare the three different temperature levels. Whatconclusions can you draw?

Heights (cm) and weights (kg) are measured for 100 randomly selected adult males, and range from heights of 134 to 192 cm and weights of 40 to 150 kg. Let the predictor variable x be the first variable given. The 100 paired measurements yield x = 166.94 cm, y = 81.26 kg, r= 0.352, P-value = 0.000, and y = - 101 + 1.04x. Find %3D the best predicted value of y (weight) given an adult male who is 145 cm tall. Use a 0.10 significance level. The best predicted value of y for an adult male who is 145 cm tall is kg.

A water hose manufacturer has developed a light-weight hose for home owners. Besides being constructed of a lightweight material. one of the characteristics of the hose is that it shrinks when it is not in use. When in use, the length of hose extends to its advertised length of 50 feet. Twenty hoses are tested to see if the hoses extend to the length of 50 feet. The sample mean of the length of the hoses is 49 1/2 feet with a s of 15 inches. Test the hypothesis at alpha = .01 that the hoses are not equal to 50 feet.
