Case Study-Statistics

In 2006, there were about 11 million commercial flights in the United States. If

one is selected at random, what is the probability that it involved a fatal accident?

3. Is a binomial distribution a good model for determining the probability of various

numbers of fatal accidents during a year?

Explain your reasoning and include a

discussion of the four criteria for a binomial experiment. Make sure you clearly

think through each criterion.

4. Suppose that the probability of a fatal accident in a given year is 0.0000004.

Construct a binomial distribution for n = 11,000,000 and

p = 0.0000004 (from above) as well as p = 0.0000008 with x = 0 to 12.
