4. Assume the average time calories burned per day for a particular population was 2400 with standard deviation of 300 Assume they all eat exactly 1600 worth of calories per day. A common saying is that you must burn a net of 3600 calories to lose a pound of fat (it is more complicated than that!). Another way of saying this is the difference between what they have ate and what they burned must be 3600 calories to lose one...
A call center receives an average of 18 calls per hour. Assuming the number of calls received follows the Poisson distribution, determine the probability would receive exactly 11 calls. Make sure that your answer is between 0 and 1.
