- pplease helparrow_forwardQ. 4 GAME THEORYarrow_forwarddepending The owner of a chain of mini-markets wants to compare the sales performance of two of her stores, Store 1 and Store 2. Sales can vary considerably on the day of the week and the season of the year, so she decides to eliminate such effects by making sure to record each store's sales on the same 12 days, chosen at random. She records the sales (in dollars) for each store on these days, as shown in the table below.

The odds of working for men are 0.62 B. the odds of working are 0.62 times as large among men compared to women C. the odds of working are 0.62 times as large women compared to men D. the odd of working for women are 0.62arrow_forwardPlease please answer all subparts. I will really upvote. Thank youarrow_forwardInvesting: Inverse ETFS (Exchange Traded Funds) Inverse ETFS, sometimes referred to as "bear market" or "short" funds, are designed to deliver the opposite of the performance of the index or category they track, and so can be used by traders to bet against the stock market. The following table shows the performance of three such funds as of August 5, 2015.t Year-to-Date Loss (%) MYY (ProShares Short Midcap 400) 6 SH (ProShares Short S&P 500) 5 REW (ProShares UltraShort Technology) 7 You invested a total of $6,000 in the three funds at the beginning of 2011, including an equal amount in MYY and SH. Your total year-to-date loss amounted to $360. How much did you invest in each of the three funds? MYY $ SH REW $ %24 %24 %24arrow_forward
- The payoff matrix and strategies P and Q (for the row and column players, respectively) are given. Find the expected payoff E of each game. (Round your answer to two decimal places.) E = 31 [32] [33] -4 5 5 P.= Show My Work (Optional)? Q = 7arrow_forwardI’m taking a probability and statistics math class. Please get this correct so I can study.arrow_forwardedo exercises 17 and 18 in section 8.1 of your textbook, about the small animal who lives in an area with woods and meadows, using the following data:If the animal is in the woods on one observation, then it is twice as likely to be in the woods as the meadows on the next observation. If the animal is in the meadows on one observation, then it is three times as likely to be in the meadows as the woods on the next observation.Assume that state 1 is being in the meadows and that state 2 is being in the woods.(1) Find the transition matrix for this Markov process. (2) If the animal is initially in the woods, what is the probability that it is in the woods on the next three observations? (3) If the animal is initially in the woods, what is the probability that it is in the meadow on the next three observations?arrow_forward
- helparrow_forwardGunfighters A, B, and C are to fight a three-cornered pistol duel. All know that A’s chance of hitting the target is 0.3, C’s is 0.5, and B never misses. They are to fire at their choice of target in succession in the order of A, B, and C, cyclically (but a hit man loses his turn and is no longer shot at) until only one man is left unhit. What should A’s strategy be? a. Shoots B first b. shoots the ground c. shoot C first d. Shoot himselfarrow_forwardFind the saddle point of the game given by the payoff matrices A below.arrow_forward
