- If customer interarrival times are exponentially distributed with rate 5 customers per hour, then O There is a 8.2% chance that a customer arrives within 5 minutes. There is a 81.8% chance that a customer arrives within 30 minutes. None of the answers are correct. There is a 34.1% chance that a customer arrives within 10 minutes. O There is a 71.3% chance that a customer arrives within 15 minutes.the length of the shower in a tropical island during rany season has a exponential Dstributed with mean 1/2. What is the probability that a shower will laast for more than 3 minutes . if a shower has already lasted for 2 minutes.What is the probability thta it will last atleast for 1 more minuteA company is planning to replace all 10,000 of the light bulbs with new energy saving bulbs. These bulbs have a lifetime that follows an exponential distribution with mean of 4,000 hours. If all the companies lights are on nine hours a day and five days a week, approximately how long will it be before the company has to replace the first bulb? Approximately how long, in weeks, will it be before they need to replace the last of these 10.000 bulb?
- The time (in years) after reaching age 60 that it takes an individual to retire is approximately exponentially distributed with a mean of about 7 years. Suppose we randomly pick one retired individual. We are interested in the time after age 60 to retirement. In a room of 1,000 people over age 81, how many do you expect will NOT have retired yet? (Round your answer to the nearest whole number.)The life (in months) of a certain computer component is exponentially distributed with mean 5. Find the probability that a component randomly selected will last between 14 and 21 months?Suppose that the length of long distance phone calls, measured in minutes, is known to have an exponential distribution with the average length of a call equal to $18 minutes. The probability that the length of a phone call is between 14 and 19 is P(14 ≤ x ≤ 19) = The 68th percentile is a phone call that lasts minutes.
- The lifetime, in years, of a certain type of electrical switch has an exponential distribution withan average lifetime of 2 years. Question. For a single system, what is the probability we can keep one switching mechanismoperable for 10 years if we assume we can replace a switch due to failures up to three timesduring the 10-year period?The amount of time that a surveillance camera will run without having to be reset is a r.v. X having exponential distribution with = 50 days. Find the prob that such a camera (a) will have to be reset in less than 20 days. (b) will not have to be reset in at least 60 days.DLP projectors are used in the majority of cinema projection systems and require a special light bulb to display a picture. Assume that the average life of a DLP bulb is 2,000 hours and that this failure time follows the exponential distribution. Answer the following questions, performing all computations with Excel functions.
- One of the factors that determines the degree of risk a pesticide poses to human health is the rate at which a pesticide is absorbed into skin after contact. An important question is whether the amount in the skin continues to increase with the length of the contact, or whether it increases for only a short time before leveling off. To investigate this, measured amounts of a certain pesticide were applied to 20 samples of rat skin. Four skins were analyzed at each of the time intervals 1 , 2 , 4 , 10 , and 24 hours. The amounts of the chemical (in micrograms) that were in the skin are given in the following table. Duration Amounts Absorbed 1 1.8 1.9 1.8 2.2 2 1.5 2.4 1.5 2.5 4 1.5 2.7 1.3 1.9 10 1.3 1.5 1.4 2.6 24 1.8 1.3 2.3 1.8 Construct an ANOVA table. Round your answers to four decimal places. One-way ANOVA: Pesticide Amount…An October 26, 2020 news report raised alarms that the population of North Atlantic Right Whales had declined a dramatic 11% with increased risk for the whales extinction in the near future. Whale deaths are largely caused by collisions with fishing boats and by whale entanglement in fishing nets and lobster trap gear. “Since the population peaked at 481 whales in 2011, there have been 103 births, but roughly 218 whales have died, presumably because of human activity – a rate of 24 deaths per year.” Subtracting births from death, what is the yearly net decrease in the Right Whale population between 2011 and 2020? Create a linear mathematical model for the decline in Right Whale population since 2011 (i.e. let 2011 be year zero). The article says that in 2018 there were 366 Right Whales counted. How accurate is your linear model when compared to the 2018 whale count?Personal care aide is an occupation that is growing quickly. Assume that, in a certain region, there will be a need for 195,686 personal care aides in 2024, a growth of about 29% over 2014 levels. How many personal care aides were there in this region in 2014?
