Thank you so muchIn laparoscopic surgery, a video camera and several thin instruments are inserted into the patient's abdominal cavity. The surgeon uses the image from the video camera positioned inside the patient's body to perform the procedure by manipulating the instruments that have been inserted. The Top Gun Laparoscopic Skills and Suturing Program was developed to help surgeons develop the skill set necessary for laparoscopic surgery. Because of the similarity in many of the skills involved in video games and laparoscopic surgery, it was hypothesized that surgeons with greater prior video game experience might acquire the skills required in laparoscopic surgery more easily. Thirty‑three surgeons participated in the study and were classified into three categories, never used, under three hours, and three or more hours—depending on the daily number of hours they played video games at the height of their video game use. They also performed Top Gun drills and received a score based on the time to…
- In the Chernobyl nuclear accident it is estimated that 30,000 people received an average dose of 45 REM. For this population, using the linear hypothesis, how many "normal" deaths from cancer are expected and how many additional deaths from the radiation of the accident? Group of answer choices 500 normal, 6000 additional 1000 normal, 4000 additional 2000 normal, 3000 additional 4000 normal, 1000 additional 6000 normal, 500 additionalXYZ Manufaturing company has hired a new VP (D.A.King) for managing capacity investment decisions. Mr. King reviews the situation after he comes on board and decides that he can invest in Batch manufacturing, Custom manufacturing or Group technology. Mr. King will not be able to forecast demand accurately till after the technology choices are made. Demand will be classified into four scenarios: poor, fair, good and excellent. The table below indicates the payoffs for each combination of technology choice and demand scenario. POOR FAIR GOOD EXCELLENT PROBABILITY 0.1 0.4 0.3 0.2 Batch - $200,000 $1,000,000 $1,200,000 $1,300,000 Custom $100,000 $300,000 $700,000 $800,000 Group Technology - $1,000,000 -$500,000 $500,000 $2,000,000 1.What is the expected monetary value of choosing the Group Technology option? 2.What is the expected monetary value of choosing the Batchoption? 3What is the BEST decision based on…CWD Business systems maintains a successful Telecom sales department for Top up call creditin which a clerk takes orders by telephone. If the clerk is occupied on one line, incoming phonecalls to the department are answered automatically by an answering machine and asked to wait.As soon as the clerk is free, the party that has waited the longest is transferred and answered first.Calls come in at a rate of about 15 per hour. The clerk is capable of taking an order in an averageof 3 minutes. Calls tend to follow a Poisson distribution, and service times tend to be exponential.The clerk is paid $15 per hour, but because of lost goodwill and sales, CWD loses about $30 perhour of customer time spent waiting for the clerk to take an order. Part B CWD is considering adding a second clerk to take calls. The store would pay that person thesame $15 per hour.Using appropriate formula for the multiple channel model, answer the following questions. a. What is the probability that no customers are…
- Trematodes of the species Euhaplorchis californiensis may infect the California kill fish, Fundulus parvipinnis. Researchers have observed that infected fish spend excessive time near the water surface, where they may be more vulnerable to bird predation. Researchers set up an experiment in a large outdoor tank that stocked with three kinds of killifish, uninfected, lightly infected, and highly infected, and recorded the number of fish that is eaten by birds. State the null and alternative hypothesisKnowing that people have a tendency to engage in social loafing when they think there are other people around to take some of the burden, researchers think that knowing they are “alone” versus “together” will impact the way a participant performs during a tug-of-war task. In the “alone” condition, participants are blindfolded and asked to pull as hard as they can on a rope against another participant on the other end. In the “together” condition, participants are once again blindfolded and told to pull as hard as they can. However, they are led to believe that there are three people on each end of the rope (they have two team additional team members to help them). The researchers find that those in the “alone” condition pull much harder (as measured by a weight sensor that measures pounds per square inch on a scale from 0 to 500 pounds) than those in the “together” condition. Which of the following is the independent variable? Pulling strength Weight sensor Social loafing…Knowing that people have a tendency to engage in social loafing when they think there are other people around to take some of the burden, researchers think that knowing they are “alone” versus “together” will impact the way a participant performs during a tug-of-war task.

Changes in stock price are independent of one another.A management consulting firm has four types of professionals on its staff: Managing consultants, senior associates, field staff and office staff. Average rates charged to consulting clients for work of each of these professionals categories are k3150/hour, k1680/hour, k1260/hour and k630/hour, respectively. Office records indicate the following number of hours billed last year in each category: 8,000, 14,000, 24,000 and 35,000, respectively. If the firm is trying to come up with an average billing rate for estimating client charges for next year, what would you suggest they do and what do you think is the appropriate rate?
