The time between incoming phone calls at a call center is a random variable with exponential density: There is a 50% probability of waiting 30 seconds or more between calls. What is the average time between calls? (Round your answer to two decimal places ) average time: seconds
Added by Emilia H.
Step 1
Given that the probability density function is lambda e^(-lambda*t), we have: 0.5 = ∫(30, ∞) lambda e^(-lambda*t) dt Solving for lambda, we get lambda = log(2)/30 ≈ 0.0231 Show more…

The probability that your call to a service line is answered in less than 30 seconds is 0.75. Assume that your calls are independent. (a) What is the probability that you must call five times in order for two of your calls to be answered in less than 30 seconds? (b) What is the mean number of calls to obtain two answers in less than 30 seconds?
