The data in Table 1.6.1 were extracted from a study designed to evaluate the effect of salt ingestion on blood pressure for hyper tense patients. Specify statistical models to answer the study question, stating the assumptions and indicate the appropriate methods for analysis of the data. Suppose now that the high sodium values for subjects 2 and 9 were erroneously recorded and thus that the actual values must be considered as missing. What changes must be introduced in the statistical models and analyses to account for the missing data?
