- At the end of summer, the total weight of seeds accumulated by a nest of seed-gathering ants will vary from nest to nest. If the total weight of seeds accumulated by a nest is exponentially distributed with parameter λ = 1/5, (a) What is the probability that the total combined weight of the seeds gathered by 100 nests will be larger than 4 95 pounds by the end of next summer? (b) What is the probability that the average weight of the seeds gathered by the 100 nests is larger than 5.3 ? (c) What assumptions are you making to answer parts (a) and (b)? Do you think those assumptions make sense in the context of this problem? Explain. (d) Tell us about the possibility that the total combined weight of the seeds gathered by 2 nests follows a normal distribution. Justify your answer in the specific context of this problem (ants, nests, seed-gathering). That is, do not just make generic statements that you think apply to every context in the world.Suppose that the number of years that a used car will run before a major breakdown is exponentially distributed with an average of 0.25 major breakdowns per year. (a) If you buy a used car today, what is the probability that it will not have experienced a major breakdown after 4 years? (b) How long must a used car run before a major breakdown if it is in the top 25% of used cars with respect to breakdown time?The life expectancy in years of a component in a microcomputer is exponentially distributed, and 1/3 of the components fail in the first 3 years. The company that manufactures the component offers a 1-year warranty. What is the probability that a component will fail during the warranty period?
- The life expectancy in years of a component in a microcomputer is exponentially dis-tributed, and 1/3 of the components fail in the first 3 years. The company that manufactures the component offers a 1 year war-ranty. What is the probability that a component will fail during the warranty period?The number of miles that a particular car can run before its battery wears out is exponentially distributed with an average of 5,000 miles. Hence, the probability that the lifetime of the battery is greater than 5000 miles is 0.368. The car has already completed a 10000-mile trip without any battery failure, what is the probability that the car will be able to complete another 5000-mile trip without having to replace the car battery? a). 0.368 b). 0.135 c). 0.632 d).1suppose that a weather station has four electronic wind gauges an gauges an orginal and three backup gauges the life time of a gauge is exponentially distributed with a mean = 300 hours what is the probability that the time until the last gauge wears out (sum of the four gauges liftime) is at least 900 hours ?
- Suppose that there are two identically-looking batteries in a box. The first one should last for a time that is exponentially distributed with parameter λ1 = 1 (in months). The second one should last for a time that is exponentially distributed with parameter λ2 = 2. A battery has been picked randomly and is still working after two months. Given this information, what is the probability that the first battery was picked?The probability that at least one computer is available at any time in the “Log-On Café” is 0.75. If you made 16 visits to the café, what is the probability that one computer would be available on exactly 10 occasions? If you made 30 visits to the café, what is the probability that one computer would be available at least 20 occasions?Let the time until the breakdown of a circuit element be exponentially distributed. If the probability that this time is more than 10^4 hours is e^(-2), what is Lambda .
- In a large city, there are 4549 lamps. we know that the lifetime of a lamp is exponential with a mean of 14 months (assume each month has 30 days), and the lifetime for different lamps is independent. At the beginning of the year all the lamps work fine. when a lamp gets damagedit replaced immediately.What is the probability that no lamp will be replaced between 02:00-03:00 AM on 01/02 (February 1st)?So the Probability of the athlete beating a hilltime of 2.27 seconds on 4 or more of the 10 gate starts, will be 99.99%?The problem of traffic delay in a highway can be studied in the following way. Let us assume that the probability of no traffic delay in one period, given no traffic delay in previous period, is 0.85 and that the probability of finding a traffic delay in one period, given a delay in the previous period is 0.75. The period of time is 30 minutes. 1- Verify if one important assumption of the model should be questioned. Explain why.
