An article in the Journal of Strain Analysis (1983, Vol. 18, No. 2) compares several methods for predicting the shear strength for steel plate girders. Data for two of these methods, the Karlsruhe and Lehigh procedures, when applied to nine specific girders, are shown in the accompanying Table. Construct a 95% confidence interval on the difference in mean shear strength for the two methods. Round your answer to four decimal places (e.g. 98.7654). ≤HD ≤ i i Girder Karlsruhe Method Lehigh Method Difference d; $1/1 0.112 $2/1 $3/1 $4/1 $5/1 $2/1 $2/2 $2/3 $2/4 1.182 1.157 1.332 1.346 1.204 1.402 1.355 1.540 1.561 1.070 0.999 1.073 1.062 1.069 1.170 1.039 1.096 1.047 0.158 0.259 0.284 0.135 0.232 0.316 0.444 0.514
