(1 point) Suppose that the time (in hours) required to repair a machine is an exponentially distributed random variable with parameterA- 0.6. What is (a) the probability that a repair time exceeds 10 hours? (b) the conditional probability that a repair takes at least 11 hours, given that it takes more than 8 hours?

CSCI 101 Here is a simple heuristic (approximation algorithm) for routing a message from node A to node B in a reasonable amount of time. The algorithm assumes that every node in the network has at least two outgoing links. (2 points) 8. Assume A has n outgoing links, n 2 2, with delays to the nodes on the other end of a1, a2, an. Select the link with the shortest delay and send the message on that line. If...

You want to buy a box of true at a chocolate store. (a) The time T (in minutes) you wait for service at the chocolate store is exponentially distributed. If the median waiting time is 5 minutes, what is the mean waiting time? [4] (b) The weights W (in grams) of boxes of true at the store are normally distributed with mean 200 grams and the standard deviation is 20 grams. What is the probability that the box of true...

Reaction time studies are studies in which participants receive a stimulus and the amount of time it takes for them to react is measured. In one simple type of reaction time study, each participant holds a clicker button and stares at a screen. When the participant sees a part of the screen light up, he or she clicks the button as quickly as possible. The researcher then records how much time elapsed between when the screen lit up and when...

1. A device that continuously measures and records seismic activity is placed in a remote region. The time T, failure of the device is exponentially distributed with mean 3 years Since the device will not be monitored during its first two years of service, the time to discovery of its failure is X max(T, 2). Then E(X) - 2. The loss due to fire in a commercial building is modelled by a random variable X with probability density function f(x)-(0.00020-x)...

The arrival time t(in minutes) of a bus at a bus stop is uniformly distributed between 10:00 A.M. and 10:03 A.M.
The arrival time t(in minutes) of a bus at a bus stop is uniformly distributed between 10:00 A.M. and 10:03 A.M. (a) Find the probability density function for the random variable t. (Let t-0 represent 10:00 A.M.) (b) Find the mean and standard deviation of the the arrival times. (Round your standard deviation to three decimal places.) (с) what is the probability that you will miss the bus if you amve at the bus stop at 10:02 A M ? Round your answer...

Guppose the time between buses at a particular stop is a positively skewed random varlable with an average of 50 minutes and standard deviation of 5 minutes. Suppose the time between buses at this stop is measured for a randomly selected week, resulting in a random sample of t= 35 t mes. The average of this tampi x, is a randon an able that comes from a specific probability distribution. (ajwhich of the following is true about the...
