Suppose the data on trees destroyed by deer in Example 4.3 had been obtained by sampling a 100-acre forest.
a. What is the estimated number of young trees destroyed by deer in the entire forest?
b. Set an upper 90% confidence limit for this estimate to get an upper bound for the total number of trees destroyed in the entire forest.
1. If it is known that the probability of having a bad reaction to a certain injection is 0.001, what is the probability that more than 1 person in 100 will have a bad reaction?
2. If the rate of accidental drownings per year is 0.000003 (i.e., 3 per 1,000,000 population), what is the probability that there will be more than 2 drownings in a city with a population of 400,000?
