Document Summary
Errors in measuring the time of arrival of a wave front from an acoustic source sometimes have an approximate beta distribution. Suppose that these errors, measured in microseconds, have approximately a beta distribution with = 1 and = 2. a what is the probability that the measurement error in a randomly selected instance is less than . 5. Give the mean and standard deviation of the measurement errors. Step-1: given that the errors in measuring the time of arrival of a wave front an acoustic source sometimes have an approximate beta distribution with and. A random variable y is said to be have an beta probability distribution with parameter and if and only if the density function of y is. To find the probability that the measurement errors in a randomly selected instances is less then 0. 5 is given by. Step-4: for the random variable y, we need to find the.
