class time: 1. (5 pts) According to genetics law while crossing black and pale color seeds of amaranth grains, we should get black, brown and pale color in the second generation according to 3 3 12:3:1 ratio respectively, i.e probabilities of the colors are : respectively. 4 16 16 Following data gives counts of different color seeds in the second generation: 1 seed color count: Black 321 Brown 77 Pale 31 Does the data follow the above genetic model? Test using Chi-square GOF test, use a=0.01 Hypotheses: H. HA test statistics: p-value: Null Rejected?: YES NO Answer question posed: (select one) Data follows genetic model Data does not follow genetic model 2. (5 points) Blood types of malaria patients at a clinic in India were compared to those obtained in a random sample of visitors to nearby hospital. Data is shown in a table below.
