Wallace, the proportion of blood 14.2 Grill A, B, AB, and O in a population of Caucasian, all in the United States is the .41, .10, .04, and .45, respectively. In order to determine the proportion of the population that truly exists in the group, according to the report. So there are some 200 Americans sampling of people and saving blood. Fees and charges due to the expectation is shown in the table are calculated with the expectation value of 14.2 Ei = 200pi inserted images of substance, test heed, the proportion of blood type, these.Table 14.2 shaft end caps the amount of blood.A B AB OThe observed values (Oi) 89 18 12 81.Expectation value (Ei) 82 20 8 90How to make the assumption that the test is determined by probability patterns.Ho : p1 = .41; p2 = .10; p3 = .04; p4 = .45WithHa: there is at least 1/4 of the probability that is different from the value specified.X2 = ∑(Oi – Ei)2 / Ei= (88-82) 2/82 + ... + (81-90) 2/90.= 3.70From table 5 in Appendix I with df = (k-1) = 3, you can find out whether the value of the test statistic observations less than 2.100 χ = 6.25 p values greater than .10, so therefore you do not have enough evidence to reject Ho, that is, you cannot tell if your blood type is different from Caucasian Americans who reported. The effect is not significant.You can find the instructions in the section "My MINITAB" at the end of this article, that allows you to test the.
