Genetic theory states that children having, one parent of blood type M and the other of blood type N will always be of one of the thrce types M, MN, N and that the proportion of these types will on the average "Of 162 children having one M parent and one N parent, 28.4% were found to be of type M, 42% of type MN and the remainder of the type N. The low value of 72 demonstrates be 1:2: 1. A report states, the truth of the genetic theory." Calculate the value of ", make the appropriate test of significance and comment on the conclusions quoted. (P.U., B.A./B.3c 973) A machine is supposed to mix peanuts, hazelnuts, cshews, and pecans in the ratio 5: 2 : 2: 1. A can containing 500 of these mixed nuts was found to have 269 peanuts, 112 hazclnuts, 74 cashews, and 45 pecanz. At the 0.05 level of significance, test the hypothesis that the machine is mixing the nuts in the supposed ratio. STATIST(@S., B.A/B.Sc. 1988)
