Homework Answers
Solution:
Given the following
information:
P(A) = 0.45
P(B) = 0.41
P(A and B) = 0.1
P(B given A) = 0.22
We have to find P(A or B)
P(A or B) = P(A) + P(B) – P(A and B)
P(A or B) = 0.45 + 0.41 - 0.10
P(A or B) = 0.76
Required probability = 0.76

Historically, the proportions of all Caucasians in the United States with blood phenotypes A, B, AB, and O are 0.41, 0.10, 0.04, and 0.45, respectively. To determine whether current population proportions still match these historical values, a random sample of 200 American Caucasians were selected, and their blood phenotypes were recorded. The observed numbers with each phenotype are given in the following table. 8817 13 2 (a) Is there sufficient evidence, at the 0.05 level of significance, to claim that...
