The proportions of blood phenotypes A, B, AB, and O in the population of all Caucasians in the United States are .41, .10, .04, and .45, respectively. To determine whether or not the actual population proportions fit this set of reported probabilities, a random sample of 200 Americans were selected and their blood phenotypes were recorded. The observed and expected cell counts are shown in Table 14.2. The ex- pected cell counts are calculated as E; = 200p;. Test the goodness-of-fit of these blood phenotype proportions. Counts of Blood Phenotypes A B AB O Observed (0) 89 18 12 81 Expected (E₁) 82 20 8 90

The proportions of blood phenotypes A, B, AB, and O in the population of all
Caucasians in the United States are .41, .10, .04, and .45, respectively. To determine
whether or not the actual population proportions fit this set of reported probabilities,
a random sample of 200 Americans were selected and their blood phenotypes were
recorded. The observed and expected cell counts are shown in Table 14.2. The ex-
pected cell counts are calculated as E; = 200p;. Test the goodness-of-fit of these blood
phenotype proportions.
