In a Maritz poll of adult drivers conducted in July 2002, 45.8% said that they "often" or "sometimes" eat or drink while driving. Assume that this result is true for the current population of all adult drivers. A sample of 18 adult drivers is selected. Let x be the number of drivers in this sample who "often" or "sometimes" eat or drink while driving. Keep your answer to 4 decimal places a) what is the probability of selecting excatly 10 adult drivers P = b) Find the mean and standard deviation of the probability distribution of x. mean = Round to 2 decimal plce Standard deviation = Round to 2 decimal place
