Data has been acccumulated on the heights of children relative to their parents. Suppose that the probabilities tthat a tall parent will have a tall, medium-height, or short child are 0.6, 0.2, and 0.2, respectively; the prob­abilities that a medium-height parent will have a tall, medium-height, or short child are 0.1, 0.7, and 0.2, re­spectively; and the probabilities that a short parent will have a tall, medium-height, or short child are 0.2, 0.4, and 0.4, respectively. (a) Write down the transition matrix for this Markov chain. (b) What is the probability that a short person will have a tall grandchild? ( c) If 20% of the current population is tall, 50% is of medium height, and 30% is short, what will the distribution be in three generations? ( d) What proportion of the population will be tall, of medium height, and short in the long run

Question

Data has been acccumulated on the heights of children relative to their parents. Suppose that the probabilities tthat a tall parent will have a tall, medium-height, or short child are 0.6, 0.2, and 0.2, respectively; the prob­abilities that a medium-height parent will have a tall, medium-height, or short child are 0.1, 0.7, and 0.2, re­spectively; and the probabilities that a short parent will have a tall, medium-height, or short child are 0.2, 0.4, and 0.4, respectively. (a) Write down the transition matrix for this Markov chain. (b) What is the probability that a short person will have a tall grandchild? ( c) If 20% of the current population is tall, 50% is of medium height, and 30% is short, what will the distribution be in three generations? ( d) What proportion of the population will be tall, of medium height, and short in the long run
