According to the National Highway Traffic Safety Administration, the average age of a driver involved in a fatal crash is 39.4 years, with a standard deviation of 17.4 years. Suppose a random sample of 50 drivers involved in a fatal crash is selected. [Source: https://crashstats.nhtsa.dot.gov/Api/Public/ViewPublication/810853] What is the probability that the average age of drivers involved in fatal crash in the sample exceeds 41? Question 24 options: A) 0.5359 B) 0.4641 C) 0.7422 D) 0.2578 E) 0.6502
The U.S. National Highway Traffic Safety Administration gathers data concerning the causes of highway crashes where at least one fatality has occurred. From the 1998 annual study, the following probabilities were determined (BAC is blood-alcohol level): ?(???=0|Crash with fatality)=0.625 ?(??? is between .01 and .09|Crash with fatality)=0.302 ?(??? is greater than .09|Crash with fatality)=0.069 Suppose over a certain stretch of highway during a 1-year period, the probability of being involved in a crash that results in at least one fatality...

2. A car rental agency has 8 compact cars and S mid-size cars. If four of the cars are selected at random and without replacement, what is the probability of getting a) two cars of each type b) at least three mid-size cars
NHTSA crash tests. Refer to the National Highway Traffic Safety Administration (NHTSA) crash tests of new car models, presented in Exercise. A summary of the driver–side star ratings for the 98 cars in the CRASH file is reproduced in the accompanying MINITAB printout. Assume that 1 of the 98 cars is selected at random, and let x equal the number of stars in the car’s driver–side star rating.a. Use the information in the printout to find the probability distribution for...
The U.S. Department of Transportation, National Highway Traffic Safety Administration, reported that 77% of all fatally injured automobile drivers were intoxicated. A random sample of 31 records of automobile driver fatalities in Kit Carson County, Colorado, showed that 18 involved an intoxicated driver. Do these data indicate that the population proportion of driver fatalities related to alcohol is less than 77% in Kit Carson County? Use α = 0.01. Solve the problem using both the traditional method and the P-value...

18. Suppose the National Highway Safety Traffic Administration (NHSIA 1 Highway Safety Traffic Administration (NHSTA) wishes to study the average dom sample of 1372 cars, weight of all American-made compact care (Chrysler. Ford, GM). From a random sample or they acquired the sample mean to be 2982 pounds with a standard deviation of 16 pounds. 88% confidence interval for the appropriate parameter (approximate the t-score using approximate the f-score using the Z-score, and assume all conditions are met). a) (2973.269,...
Please make your hand writing clear and understandable. Awarding road contracts. A state Department of Transportation (DOT) recently claimed that each of five bidders received equal consideration in the awarding of two road construction contracts and that, in fact, the two contract recipients were randomly selected from among the five bidders. Three of the bidders were large construction conglomerates and two were small specialty contractors, Suppose that both contracts were awarded to large construction conglomerates. a. b. What is the...
