Insulin-dependent diabetes (IDD) among children occurs most frequently in persons of northern European descent. The incidence ranges

Question:

Insulin-dependent diabetes (IDD) among children occurs most frequently in persons of northern European descent. The incidence ranges from a low of 1-2 cases per 100,000 per year to a high of more than 40 per 100,000 in parts of Finland. Let us assume that an area in Europe has an incidence of 5 cases per 100,000 per year.
a. Can the of the number of cases of IDD in this area be approximated by a Poisson If so, what is the mean?
b. What is the probability that the number of cases of IDD in this area is less than or equal to 3 per 100,000?
c. 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?
d. Would you expect to observe 10 or more cases of IDD per 100,000 in this area in a given year? Why or why not?
