Question:

The reliability of a piece of equipment is frequently defined to be the probability, p, that the equipment performs its intended function successfully for a given period of time under specific conditions (Heizer, Render, and Munson, Principles of Operations Management, 2016). Because p varies from one point in time to another, some reliability analysts treat p as if it were a random variable. Suppose an analyst characterizes the uncertainty about the reliability of a particular robotic device used in an automobile assembly line using the following distribution:

a. Graph the analyst's probability distribution for p.
b. Find the mean and variance of p.
c. According to the analyst's probability distribution for p, what is the probability that p is greater than .95? Less than .95?
d. Suppose the analyst receives the additional information that p is definitely between .90 and .95, but that there is complete uncertainty about where it lies between these values. Describe the probability distribution the analyst should now use to describe p.
