The life of a new miniature battery is uniformly distributed between 2 and 14 hours of continuous use. Law enforcement requires that it last at least 12.8 hours. What is the probability that X meets the law enforcement standard? 0.1 0.9 0.95 0.05 0.025 Submit Answer Tries 0/2
Assume that X is uniformly distributed random variable with mean 7 and variance 12. Find the probability that X is at most 9.4 0.15 0.7 0.3 0.075 0.85 Submit Answer Tries 0/2
The time in minutes passengers must wait for a commuter plane in a main train station is uniformly distributed on the interval [1,12].
