Q1. [Total 15 marks] Insulin-dependent diabetes (IDD) is a common chronic disorder of children. This disease occurs most frequently in persons of northern European descent. Let us assume that an area in Europe has an incidence of 6 cases per 100,000 per year. Can the distribution of the number of cases of IDD in this area be approximated by a Poisson distribution? What is the mean? What is the probability that the number of cases of IDD in this area is less than or equal to 3 per 100,0007 Round your answer to three decimal places. What is the probability that the number of cases is greater than or equal to 3 but less than or equal to 7 per 100,000? Round your answer to three decimal places. Would you expect to observe 15 or more cases of IDD per 100,000 in this area in a given year? Why or why not
