6. An automobile manufacturer is concerned about a fault in the braking mechanism of a particular model.The fault on rare occasions causes a catastrophe at high speed. Assume that the distribution of the numberof cars per year will experience the fault is 8 on the average, find the probability that (a) at most 3 cars peryear will experience a catastrophe, (b) more than 1 car per year will experience a catastrophe.

Benford's Law claims that numbers chosen from very large data files tend to have "1" as the first nonzero digit disproportionately often. In fact, research has shown that if you randomly draw a number from a very large data file, the probability of getting a number with "1" as the leading digit is about 0.301. Suppose you are an auditor for a very large corporation. The revenue report involves millions of numbers in a large computer file. Let us say you took a random sample of n = 250 numerical entries from the file and r = 60 of the entries had a first nonzero digit of 1. Let p represent the population proportion of all numbers in the corporate file that have a first nonzero digit of 1. Test the claim that p is less than 0.301 by using α = 0.01. What does the area of the sampling distribution corresponding to your P-value look like? a. The area in the right tail of the standard normal curve. b. The area not including the right tail of the standard normal curve.…
