A traditional call center has a simple mission: Agents have to answer customer calls fast and end them as quickly as possible to move on to the next call. The quality of service rendered by the call center was evaluated by ...Let y be a random variable having a normal distribution with a mean equal to 250 and a standard deviation equal to 50. Find the following probabilities: a. P(y > 250) b. P(y > 150) c. P(150 < y < 350) d. Find k such that ...A random sample of 16 measurements is drawn from a population with a mean of 60 and a standard deviation of 5. Describe the sampling distribution of y-bar, the sample mean.
