A car insurance company has determined that 4% of all drivers were involved in a car accident last year. Among the 13 drivers living on one particular street. 3 were involved in a car accident last year. If 13 drivers are randomly selected, what is the probability of getting 3 or more who were involved in a car accident last year? Round to three decimal places. O A 0.988 OB. 0.014 C. 0.602 OD. 0.012

Three different models of automobiles (A, B, and C) were compared for gasoline consumption. For each model of car, fifteen cars were randomly selected and subjected to standard driving procedures. The average miles/gallon obtained for each model of car and sample standard deviations are shown below. Car A Car B Car C Average Mile Per Gallon 42 49 44 Sample Standard Deviation 4 5 3 Use the above data and test to see if the mean gasoline consumption for all...

Among 450 randomly selected drivers in the 20-24 age bracket, 9 were in a car crash in the last year. If a driver in that age bracket is randomly selected, what is the approximate probability that he or she will be in a car crash during the next year? Is it unlikely for a driver in that age bracket to be involved in a car crash during a year? Is the resulting value high enough to be of concern to...

Please explain step by step
Suppose that the number of drivers who travel between a particular origin and destination during a designated time period has a Poisson distribution with parameter u = 20 (suggested in the article "Dynamic Ride Sharing: Theory and Practice"+). (Round your answer to three decimal places.) (a) What is the probability that the number of drivers will be at most 11? 0.011 (b) What is the probability that the number of drivers will exceed 26? (c)...

1. In a random sample of 300 Las Cruces residents who drive a domestic car, 50 reported owning a hybrid car, whereas another sample of 350 El Pas residents who drive a domestic car revealed 30 who owned a hybrid car. Assume a = .05 a. Perform a hypothesis testing procedure to determine if the proportion of Las Cruces drivers that own a hybrid car is higher than the proportion in El Paso. b. Suppose p = 0.15 and p...
