A study was conducted to examine whether protein concentration (mg/mL) impacts pancreatic function in cystic fibrosis patients. Pancreatic function was measured by trypsin secretion [U/(kg/hr)]. Prior research has shown that protein concentration in this patient population is approximately normally distributed. Protein concentrations levels were obtained for patients with three levels of trypsin secretion: 1)50, 2) 51-1,000, and 3) >1,000. The data are provided in the table below. Use these data to answer the questions below the table. Assume=0.05.

a.You begin by plotting the data to see whether there is any evidence to suggest that protein concentration levels differ across the three trypsin secretion groups. Generate an appropriate plot of the data and comment on the pattern of protein concentration across the three trypsin secretion groups.[2 Marks]

b.Run the appropriate statistical test to determine if there is a significant difference in protein concentration across the three trypsin secretion groups. What do you conclude from running this test? Provide the calculation and/or SPSS output to support your answer.[1 Mark]
