Unformatted text preview: 75 in problem 3, compute the probability that Av 75 will be between 3.5 and 3.6. 5. The breakdown voltage of a randomly chosen diode of a particular type is known to be normally distributed with mean 40 volts and standard deviation 1.5 volts. (At this voltage the diode turns into a conductor with dire consequences for the associated power supply.) Find the probability that the breakdown voltage lies between 39 and 42 volts. 6. The following function is a candidate for use as a probability density function: f ( x ) = b 1 8 + A x for 0 ≤ x ≤ 2 otherwise a. Find the value of A which makes f ( x ) an acceptable density function. b. Compute the mean of the associated random variable. c. Compute the variance and standard deviation....
