Do you tailgate the car in front of you? About 45% of all drivers will tailgate before passing, thinking they can make the car in front of them go faster. Suppose that you are driving a considerable distance on a two-lane highway and are passed by 8 vehicles. (a) Let r be the number of vehicles that tailgate before passing. Make a histogram showing the probability distribution of r for r = 0 through r = 8.

(b) Compute the expected number of vehicles out of 12 that will tailgate. (Round your answer to two decimal places.)

(c) Compute the standard deviation of this distribution. (Round your answer to two decimal places.)

1) Suppose you have the following information. 12% of all drivers do not have a valid driver’s license, 6% of all drivers have no insurance, and 4% have neither (i.e., do not have driver’s license and do not have insurance). The probability that a randomly selected driver either fails to have a valid license or fails to have insurance is about (a) 0.18 (b) 0.2 (c) 0.22 (d) 0.072 (e) 0.14 3) Given that events A and B are mutually...

2. In 2009 it was reported that 45% of all car accidents in Buffalo were alcohol related. Suppose we take a random sample of 200 car accidents in Buffalo and let X be the number which are alcohol related. a. Define the random variable X of the form ) Find the probability that fewer than half (less than 100) were alcohol related. Find the prob. that between 60 and 80, inclusive, were alcohol related. Find the probability at least 90...

As a manager at a car insurance company, you know that out of every 100 drivers, there are 30 risky drivers and 70 safe drivers. A risky driver costs your company $5,000 per year to insure, and a safe driver costs only $500. You design a policy that you think will appeal to safe drivers and expect that out of every 100drivers insured by this policy, 20 will be risky drivers and 80 will be safe drivers. The price (premium)...
