Recent crime reports indicate that 17.3 motor vehicle thefts occur every hour in Canada. Assume that the distribution of thefts per hour can be approximated by a Poisson probability distribution.

a. Calculate the probability exactly four thefts occur in an hour.(Round the final answer to 5 decimal places.)

Probability

b. What is the probability there are no thefts in an hour? (Round the final answer to 5 decimal places.)

Probability

c. What is the probability there are at least 20 thefts in an hour? Use excel or online calculator to find the answer. (Round the final answer to 5 decimal places.)

Expert Solution

a. Calculate the probability exactly four thefts occur in an hour.

P(X = 4) = 0.00011

b. What is the probability there are no thefts in an hour?

P(X = 0) = 0.00000

c. What is the probability there are at least 20 thefts in an hour?

P(x > = 20) = 0.27187

Data from the Motor Vehicle Department indicate that 80% of all licensed drivers are older than age 25. a. In a sample of n=50 people who recently received speeding tickets, 33 were older than 25 years and the other 17 were age 25 or younger. Is the age distribution for this sample significantly different from the distribution for the population of licensed drivers? Use α= 0.05. b. In a sample of n=50 people who recently received parking tickets, 36 were...
