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

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.
