10.5.3 In a classic study of peptic ulcer, blood types were determined for 1,655 ulcer patients. The accompanying table shows the data for these patients and for an inde- pendently chosen group of 10,000 healthy controls from the same city. 34 Blood type Ulcer patients Controls O 911 4,578 A 579 4,219 B 124 890 AB 41 313 Total 1,655 10,000 (a) The value of the chi-square statistic for this contingency table is * = 49.0.
