Gastroenterology

In Table 12.39, we present data relating protein concentration to pancreatic function as measured by trypsin secretion among patients with cystic fibrosis [16].

12.42 If we do not want to assume normality for these distributions, then what statistical procedure can be used to compare the three groups?

12.43 Perform the test mentioned in Problem 12.42 and report a p-value. How do your results compare with a parametric analysis of the data?
