The expected number of births at a rural hospital is one per day. Assume that births occur independently and at a constant rate. Use R to the draw the pmf of the number of births per day at this hospital. Find the probability of observing at least 3 births in a day. Find the probability of observing at most 5 births in a week. At a larger hospital, the expected number of births per day is 17.4. Assume that births...

Consultants in a particular industry are currently paid $100 per hour and the typical work day lasts 10 hours. Demand for labour in that industry increases, resulting in the average hourly rate increasing to $150 per hour. However, a labour survey reveals that most consultants now work two fewer hours per day than they did prior to the rise in the price of their labour. A newspaper comments that this is at odds with the “law of supply”, such that...
