An article in the Journal of Strain Analysis (Vol 18, No. 2, 1983) compares several procedures for predicting the shear strength for steel plate girders. Data for the ratio of predicted to observed load for two of these procedures on 9 girders are collected using paired comparative experiment are displayed as follows:

Girder	Karlsruhe Method	Lehigh Method
S1/1	1.186	1.061
S2/1	1.151	0.992
S3/1	1.322	1.063
S4/1	1.339	1.062
S5/1	1.2	1.065
S2/1	1.402	1.178
S2/2	1.365	1.037
S2/3	1.537	1.086
S2/4	1.559	1.052

(a) Is there any evidence to support a claim that there is a difference in mean performance of the two methods? Using α = 0.05?

(b) What is the p-value for the test in part (a)?

An article in the journal Hazardous Waste and Hazardous Materials (Vol. 6, 1989) reported the results of an analysis of the weight of calcium in standard cement and cement doped with lead. Reduced levels of calcium would indicate that the hydration mechanism in the cement is blocked and would allow water to attack various locations in the cement structure. Ten samples of standard cement had an average weight percent calcium of 90.0, with a sample standard deviation of 5.0 and...

An article in the Journal of Aircraft (Vol. 23, 1986, pp.859–864) described a new equivalent plate analysis method formulation that is capable of modeling aircraft structures such as cranked wing boxes and that produces results similar to the more computationally intensive finite element analysis method. Natural vibration frequencies for the cranked wing box structure are calculated using both methods, and results for the first seven natural frequencies follow: Frequency Finite Element, Cycle/s Equivalent Plate, Cycle/s 1 14.58 14.76 2 48.52...

An article in IEEE International Symposium on Electromagnetic Compatibility (Vol. 2, 2002, pp. 667–670) describes the quantification of the absorption of electromagnetic energy and the resulting thermal effect from cellular phones. The experimental results were obtained from in vivo experiments conducted on rats. The arterial blood pressure values (mmHg) for the control group (8 rats) during the experiment are X1 = 90, s1 = 5 and for the test group (9 rats) are X2 = 115,s2 = 10. (a) Is...
