An IT company employs two sales engineers. Engineer 1 does the work of estimating cost for 70% of jobs bid by the company. Engineer 2 does the work for 30% of jobs bid by the company. It is known that the error rate for engineer 1 is such that 0.02 is the probability of an error when he does the work, whereas the probability of an error in the work of engineer 2 is 0.04. Suppose a bid arrives and a serious error occurs in estimating cost. Which engineer would you guess did the work? Explain and show all work.

An insurer writes a large book of home warranty policies. You are given the following information regarding claims filed by insureds against these policies: (i) A maximum of one claim may be filed per year. The probability of a claim varies by insured, and the claims experience for each insured is independent of every other insured. (ii) (ii) The probability of a claim for each insured remains constant over time. (iv) The overall probability of a claim being filed by a randomly selected insured in a year is 0.10. (v) The variance of the individual insured claim probabilities is 0.01. An insured selected at random is found to have filed 0 claims over the past 10 years. Determine the Bühlmann credibility estimate for the expected number of claims the selected insured will file over the next 5 years. (A) 0.04 (B) 0.08 (C) 0.17 (D) 0.22 (E) 0.25
Chase is the general manager for a business. One of Chase's tasks is to assign extra projects to his employees. These extra projects are supposed to be assigned following a particular order. The extra projects result in additional pay, so the employees are concerned that the extra projects are assigned following the proper procedure. Errors do happen though. Chase makes an error once every 54 tasks that he assigns. If Chase were to assign 10 tasks, what is the probability that he would make 3 or more mistakes? .000023 (Round your answer to six decimal places.) When Chase was supposed to assign 10 tasks to Kendra, he DID make 3 mistakes. Was Kendra treated fairly? yes or no What conclusions could you make about the three mistakes? Make sure to explain your conclusion thoroughly.
A market analyst studying the length of time shoppers spend in two types of grocery store observes a sample of 75 shoppers in each store. The mean time the sample of shoppers spends in Store A is 55minutes. The mean time the sample of shoppers spends in store B is 49 minutes. What is the probability of observing a sample difference X-BarA – X-BarB at least as large as and in the same direction as this if there is no difference in the true mean time that shoppers spend in the two stores and if the standard deviation is 15 minutes for both populations? What assumptions are made regarding the samples
Engr. Sasuke of Hokage Design and Build Company has two bidding appointments on a given day. At the first appointment, he believes that he has a 80% chance to make the deal, from which he can earn 10,000 pesos commission if successful. On the other hand, he thinks he only has a 45% chance to make the deal at the second appointment, from which, if successful, he can make 15,000. What is his expected commission based on his own probability belief? Assume that the appointment results are independent of each other. a) 20,750 b) 17,750 c) 15,750 d) 14,750
The mean of the time it takes for a product to arrive from China is 60 days and the standard deviation is 10 days. What is the probability that if 2 products are ordered from China, each of them will take 70 or more days to arrive. Assume that the arrival time of these 2 products are independent.
A local fan club plans to invest 19,429 to host a soccer game. The total revenue from the sale of tickets is expected to worth 70,182. But if it rains on the day of the game, they won't be able to sell any tickets, and the club will lose all the money invested. If the weather forecast for the day of the game is with 15 chance of rain, calculate to see if there is going to be an expected profit or an expected loss. Note: Please avoid rounding numbers in the middle of your calculations.
This question has several parts that must be completed sequentially. If you skip a part of the question, you will not receive any points for the skipped part, and you will not be able to come back to the skipped part. Tutorial Exercise Phone calls arrive at the rate of 36 per hour at the reservation desk for Regional Airways. (a) Compute the probability of receiving six calls in a 5-minute interval of time. (b) Compute the probability of receiving exactly 10 calls in 20 minutes. (c) Suppose no calls are currently on hold. If the agent takes 5 minutes to complete the current call, how many callers do you expect to be waiting by that time? What is the probability that none will be waiting? (d) If no calls are currently being processed, what is the probability that the agent can take 6 minutes for personal time without being interrupted by a call?
There are N sites that need protection (number them 1 to N). Someone is going to pick one of them to attack, and you must pick one to protect. Suppose that the attacker is going to attack site i with probability q;. You plan on selecting a site to protect, with probability pi of selecting site i. The choice of {qi} and {p;} represent the attacker's and defender's strategy, respectively.
A construction company employs two sales engineers. Engineer 1 does the work of estimating cost for 70% of jobs bid by the company. Engineer 2 does the work for 30% of jobs bid by the company. It is known that the error rate for engineer 1 is such that 0.02 is the probability of an error when he does the work, whereas the probability of an error in the work of engineer 2 is 0.04. Suppose a bid arrives and a serious error occurs in estimating cost. What is the probability that Engineer 1 did the work?
