Gabe believes his only option is to quickly steal a cookie while his mother is out of the room. Judy then leaves the room to look for Gabes backpack. Assume that judy could return at any time in the next 60 seconds with equal probability . For the first 20 seconds, Gabe sheepishly wonders if he will get caught trying to grab a nearby cookie. After waiting and not seeing his mother , Gabe decides that he needs a cookie and begins to take one from the jar. Assuming it takes Gabe 30 seconds to grab a cookie from the jar and devour it without a trace, what is the…
A large family travelling on the road in convoy decided to stop at a bed and breakfast since it was getting pretty late. However, there were too many people so they decided to split up to 3 nearby bed and breakfasts. 40% of the family members stayed at B&B 1, 35% stayed at B&B 2, and 25% stayed at B&B 3. According to feedback, 6% of the rooms in B&B 1 have lights that do not work, 9% of rooms in B&B 2 have lights that do not work, and 7% of rooms in B&B 3 have lights that do not work. 1) Given the data above, make a venn diagram.2) Determine the probability that a family member will have a room with functional lights. 3) Determine the probability that a family member whose room lights do not work was assigned to B&B A.

Kentville, a community of 10,000 people, resides next to a krypton mine, and there is a concern that the emission from the krypton smelter have resulted in adverse effects. Specifically, Kryptonosis seems to have killed 12 of Kentville’s inhabitants last year. A neighboring community, Lanesburg, has 25,000 inhabitants and is far enough from the smelter to not be affected by the emission. In Lanesburg, only three people last year died of Kryptonosis. Given that the number of deaths in Kentville and their causes last year were: Heart attack=7 Accidents=4 Kryptonosis=12 Other=6 What is the risk of dying of Kryptonosis in Kentville relative to non-contaminated locality?What is the risk of dying of Kryptonosis in Kentville relative to deaths due to other causes? How many times the chance of dying of Kryptonosis compared to dying of accidents ? How many times the chance of dying of Kryptonosis compared to Other causes?
In a baseball game, Jim is the pitcher and Joe is the batter. Suppose that Jim can throw either a fast or a curve ball at random. If Joe correctly predicts a curve ball, he can maintain a .400 batting average, else, if Jim throws a curve ball and Joe prepares for a fast ball, his batting average is kept down to .200. On the other hand, if Joe correctly predicts a fast ball, he gets a .250 batting average, else, his batting average is only .125. (a) Define the alternatives for this situation. (b) Define the objective function for the problem and discuss how it differs from the familiar optimization (maximization or minimization) of a criterion.
In baseball, League A allows a designated hitter (DH) to bat for the pitcher, who is typically a weak hitter. In League B, the pitcher must bat. The common belief is that this results in League A teams scoring more runs. In interleague play, when League A teams visit League B teams, the League A pitcher must bat. So, if the DH does result in more runs, it would be expected that league A teams will score more runs in League A park than when visiting League B parks. To test this claim, a random sample of runs scored by league A teams with and without their DH is given in the accompanying table. Complete parts c) through d) below.
Company X has 10 employees, each placing an average of 20 minutes of long-distance calls per day. The average call lasts 5 minutes.

Calculate the traffic flow in Erlang during the busy hour.
The manager of a small store decided to make half of his employees complete a mandatory training program. Among other things, the training program teaches employees to better serve the customers, be more proactive, appropriately greet customers, etc. After completion of the training program, the manager asks the group that did not receive the training program (non-training group 1) to work for a week (week 1) and then asks the group that received the training program (training group) to work the next week (week 2). During week 1 and week 2 he collects data regarding customer satisfaction from 450 and 800 people respectively using the following item: How satisfied are you with our customers? Not satisfied at all Very Satisfied 1 2 3 4 5 6 7 For week 1 the average customer satisfaction was 4.5 and for week 2…
A school Psychologist is interested in the effect of violent television programs on a child's agression depending on if the show is a cartoon or not. Eighty children were recruited and were divided into equal groups. Half of the children watched a violent television program while the other half watched a non- violent program. Half of the children watched a cartoon while the other half watched a show that was not a cartoon. The children were then placed in a small group and the researcher measured the level of agressiveness of each child. A) z- test B) t - test C) test independent samples D) T - TEST RELATED SAMPLES E) ANOVA F) FACTORIAL ANOVA G) repeated measures ANOVA H) pearson correlation i) chi square
A car agency has offices in Phoenix, Denver and Chicago. The agency allows one- or two-way rentals so that cars rented in one location may end up in another. Statistics show that at the end of each week 70% of all rentals are twoway. As for the one-way rentals: from Phoenix, 40% go to Denver, and the rest to Chicago; from Denver, 60% go to Chicago and the rest to Phoenix; from Chicago, 40% go to Denver and the rest to Phoenix; (a) Express the situation as s Markov chain. (b) If the agency starts the week with 100 cars in each location, what will the distribution be like in two weeks (two-step transition probability matrix)? (c) If each location is designed to handle a maximum of 120 cars, would there be a long run space availability problem in any of the location?
