Context II. in a study of the relationship between dietary salt intake and increased systolic blood pressure, individuals in three subgroups. were recruited for a study. The T individuals in Group 1 were healthy controls, the 9 individuals in Group 2 were moderately obese, and the 12 individuals in Group 3 were severely obese. The amount, X, of salt consumed {in grams per week} was recorded using dietary diaries. The response, 1", a rescaled measure of excess {above normal} systolic blood pressure, was recorded at the end of the study. Five models were fitted to these data, labeled m1m5. lGeneric graphs for all of them appear below. Answer Questions Tl using the R output on pp. 5-5. A} a) C} %// / o) E) 7.
