Question

Assume that police estimate that 23 of drivers do not wear their seatbelts They set up a safety roadblock stopping cars to check for seatbelt use They stop 50 cars during the first hour 1 p a Find the mean variance and standard deviation of the number of drivers expected not to be wearing seatbelts Use the fact that the mean of a geometric distribution is b How many cars do they expect to stop before finding a driver whose seatbelt is not buckled Round to the nearest tenth as needed The variance is Round to the nearest tenth as needed The mean is The standard deviation is Do not round until the final answer Then round to the nearest tenth as needed They expect to stop cars before finding a driver whose seatbelt is not buckled Round to the nearest tenth as needed THE and the variance is o
