Data for nine girders in the form of the ratio of predicted to observed load for two of these procedures, the Karlsruhe and Lehigh methods, are as follows: Girder S1/1 S2/1 S3/1 S4/1 S5/1 S2/1 S2/2 S2/3 S2/4 Karlsruhe Method 1.186 1.151 1.327 1.338 1.115 1.101 1.365 1.337 1.259 Lehigh Method 1.061 1.092 1.075 1.061 1.065 1.079 1.137 1.086 1.052 a) Investigate the normality assumption for both samples. b) Investigate the normality assumption for the difference in ratios for the two methods. c) Is there any evidence to support a claim that there is a difference in mean performance between the two methods? Use a = 0.05. 1) State the hypotheses. ii) What is the test statistic? iii) What are the assumptions? iv) What is the p-value for the test? v) What is the decisions? vi) Make Conclusions. d) Construct a 95 percent confidence interval for the difference in mean predicted to observed load
