3. Expected value and standard deviation of the sample proportion {infinite population) A BIurayr player production line manager wants to estimate the proportion of defective BIuray players produced by his production process. Rather than checking every Blu-ray player produced, the production manager plans on taking a random sample of size 74 in order to estimate the proportion of defective Bluray players being produced by the process. If the sample proportion of defective BIu-ray players, r is greater than 0.03, the manager will consider adjusting the production process. Suppose that the true proportion of defective BIu-ray players produced by the process is p = 0.02. What is the expected value ofthe sample proportion? HP? = C What is the standard deviation of the sampling distribution ofthe sample proportion? ? || 1 || 4 4
