Each of the 50 separate Local Authorities in a country collects data on the number of road accidents in a year (n) and the number of these in which a fatality occurred (f).Question 23In order to estimate the overall proportion (in the country) of road accidents in which a fatality occurred, which one of the following is best?Compute the ratio f/n for each Local Authority, sum these ratios and divide by 50Sum all the values of f to give a total F, sum all the values of n to give a total N and compute F/NSelect one Local Authority at random, all equally likely, and use its value of f/nAs in C, except that the chance of selecting any particular Local Authority should be proportional to its population

By multiplying the total number of accidents by 1.000.000 and dividing by the actual working hours, which is the statistical ratio found?Soru 28Cevapa.Accident Frequency Rateb.Accident Probability Ratec.Accident Consequence Rated.Accident Severity Rate

The table below shows the number of deaths in the U.S. in a year due to a variety of causes. For these questions, assume these values are not changing from year to year, and that the population of the United States is 312 million people.Cause DeathsPassenger car occupant (driver or rider) 13,100Motorcycle (driver or rider) 4,500Tornado 553Skydiving 56 Hint: Does your probability of dying in a car accident next year differ much from the probability of a random person dying in a car accident?c) Estimate the probability that you will die as a passenger car occupant next year?

A car insurance company has determined that there is a 9% rate of car accidents in one year. However the insurance company finds that among a group of 200 drivers selected at random from the town of Misty Glen, 30 had accidents in the last year. If the 9% rate is correct, estimate (using a normal approximation) the probability of observing 30 or more car accidents in a random sample of 200 drivers. Is there evidence to suggest that the accident rate in Misty Glen is higher than 9%?Group of answer choices0.998; no. Suggestion is that the rate is actually lower.0.002; no. Suggestion is that accident rate in Misty Glen is no different.0.002; yes. Suggestion is that rate is actually higher for Misty Glen.0.002; no. Suggestion is that the rate is actually lower.0.998; yes. Suggestion is that the rate is actually higher for Misty Glen.

An insurance company selected 2000 drivers at random (i.e., without any preference of one driver over another) in a particular city to find a relationship between age and accidents.  The data obtained are given in the following table: Age of drivers (in years) Accidents in one year 0 1 2 3 Over 3 18-29 440 160 110 61 35 30-50 480 125 85 22 18 Above 50 360 45 35 15 9 If a driver is chosen at random from the city, find the probability for the driver being 30-50 years of age and having one or more accidents in one year

Same table as previous question) An insurance company selected 2000 drivers at random (i.e., without any preference of one driver over another) in a particular city to find a relationship between age and accidents.  The data obtained are given in the following table: Age of drivers (in years) Accidents in one year 0 1 2 3 Over 3 18-29 440 160 110 61 35 30-50 480 125 85 22 18 Above 50 360 45 35 15 9 A driver of age above 50 is selected at random. What is the probability that the driver has 2 or more accidents in a year?
