Solve the problem.A survey in a small mining town indicates that 40% of miners' sons become miners, whereas 60% do not. Also 10% of nonminers' sons become miners. At the present time, 70% of the town's men are miners and 30% are nonminers. Considering this as a Markov process:(a) Write the initial distribution matrix.(b) Write the stochastic (transition) matrix with rows and column labeled M (for miners ) and NM (for nonminers) that describes the transitions.(c) Give the percentage of the town's men who will be miners in the first generation, ...in the second generation.(d) Write the system of linear equations needed to determine the stable distribution of the town's male population.(e) Give the proportion of the town's men who will become miners in the long run.
What will be an ideal response?
(a)
| (b) | M NM |
| (c) | 31%; 19.3% |
| (e) |  |
