peruvian.txtProblem 1 (explore the data):In this exercise use the Peruvian blood pressure data set, provided in the file peruvian.txt (A NOTE for repeat students: The data is different from the data I shared last year.). This dataset consists of variables possibly relating to blood pressures of n = 30 Peruvians who have moved from rural high altitude areas to urban lower altitude areas. The variables in this dataset are: Age, Weight, Height, Pulse, Systol and Diastol. Before reading the data into MATLAB, it can be viewed in a...
