Suppose that during a manufacturing process a certain proportion of the products are flawed and have to be rejected by quality control. To determine how serious the problem is, the company tests 50 samples coming off the line and finds that 5 of them have to be rejected. use this information, and the fact that this is a Bernoulli random variable to find the maximum likelihood function for the process, and use that to calculate the most likely proportion of all parts that are flewed during manufacture.
