11. A certain mobile phone app is becoming popular in a large population. Every week 10% of those who are not using the app, either because they don't have it yet or have it but are not using it, start using it, and 15% of those who are using it stop using it. Assume that the starting percentages are that 80% are not using it and 20% are using it. (a) Show the Markov matrix A representing the situation. (Letting .80 represent the starting 1.20 .80 percentages, remember that you want the situation after one week to be given by A .) .20 (b) What percentage will be using the app after two weeks? (c) Find the eigenvalues and eigenvectors of A. (d) Show a matrix X which diagonalizes A by means of X-'AX. (d) In the long run the percentages not using the app will be Show your work. _% and using it will be _%

5. A small vegetarian shop serves only two kinds of sandwiches: falafel and tofu. The shop observes that if a customer orders a falafel sandwich, there is that they will order a falafel sandwich on their next visit. If the custômer orders a tofu sandwich, there is a 40% chance that they will order a falafel sandwich on their 70% chance next visit. (a) Give a transition matrix associated with this situation; (b) A customer shops at the sandwich shop once per week. If the customer ordered a falafel sandwich two weeks ago, what is the probability that they will order a tofu sandwich this week? (c) Find the steady state vector associated with this situation.

Why Leslie matrices are not typically Markov matrices?
An individual can contract a particular disease with probability 0.17. A sick person will recover dur- ing any particular time period with probability 0.44 (in which case they will be considered healthy at the beginning of the next time period). Assume that people do not develop resistance, so that pre- vious sickness does not influence the chances of contracting the disease again. Model as a Markov chain, give transition matrix on your paper. Find the probability that a healthy individual will be sick after two time periods.
2. A bus containing 100 gamblers arrives in Las Vegas on a Monday morning. The gamblers play only poker or blackjack, and never change games during the day. The gamblers' daily choice of game can be modeled by a Markov chain: 95% of the gamblers playing poker today will play poker tomorrow, and 80% of the gamblers playing blackjack today will play blackjack tomorrow. (a) Write down the stochastic matrix corresponding to this Markov chain. (b) If 60 gamblers play poker on Monday, how many gamblers play blackjack on Tuesday? (c) Find the unique steady-state vector for the stochastic matrix in part (a).
Draw the state diagram for the Markov Model and show the transition probabilities on the diagram.
Consider a game where you need to fill a 5-digit number by spinning a wheel. Every time you spin the wheel a random digit shows up between 0 – 9 with equal probability. You are to decide where to place the digit in your number. Once you choose a location for the digit you cannot change it. Your objective is to maximize the number you get. (a) Set this up as a Markov Decision Process, identify the states, actions, and transition matrices.
If she made the last free throw, then her probability of making the next one is 0.7. On the other hand, If she missed the last free throw, then her probability of making the next one is 0.2. Assume that state 1 is Makes the Free Throw and that state 2 is Misses the Free Throw. (1) Find the transition matrix for this Markov process. P =
1. Assume that the probability of rain tomorrow is 0.5 if it is raining today, and assume that the probability of its being clear (no rain) tomorrow is 0.9 if it is clear today. Also assume that these probabilities do not change if information is also provided about the weather before today. (a) Formulate the evolution of the weather as a Markov chain by defining its states and giving its (one-step) transition matrix. (b) Find the n-step transition matrix P(n) for n = = 2, 5, 10, 20. (c) The probability that it will rain today is 0.4. Use the results from part (b) to determine the probability that it will rain n days from now, for n = 2, 5, 10, 20.
Explain why adding a self-transition to a Markov chain makes it is aperiodic.
2. The day-to-day changes in weather for a certain part of the country form a Markov process. Each day is sunny, cloudy, or rainy. • If it is sunny one day, there is a 70% chance that it will be sunny the following day, a 20% chance it will be cloudy, and a 10% chance of rain. • If it is cloudy one day, there is a 30% chance it will be sunny the following day, a 50% chance it will be cloudy, and a 20% chance of rain. • If it rains one day, there is a 60% chance that it will be sunny the following day, a 20% chance that it will be cloudy and a 20% chance of rain. (a) Create a transition diagram that describes this scenario. (b) Create a stochastic matrix that describes this scenario. Is this scenario ergodic or absorbing? Explain. (c) Suppose that today, there is a 42% chance of sun, 38% chance of clouds, and 20% chance of rain. Using matrix multiplication, predict the weather tomorrow, next Thursday (in 7 days), and in two weeks (in 14 days). (d) Find the eigenvalues and eigenvectors…
In a laboratory experiment, a mouse can choose one of two food types each day, type I or type II. Records show that if the mouse chooses type I on a given day, then there is a 75% chance that it will choose type I the next day, and if it chooses type II on one day, then there is a 50% chance that it will choose type II the next day. (a) Find the transition matrix for this Markov chain. Is it regular? Remember this means that all the entries of some power of the matrix are positive. (b) If the mouse chooses type I today, what is the probability that it will choose type I two days from now? (c) If the mouse chooses type II today, what is the probability that it will choose type II three days from now? (d) About what percentage of the time should we expect the mouse to choose type I food? Type II?
