Espan Do you carpool? Let A represent the number of occupants in a randomly chosen car on a certain stretch of highway during morning commute hours. A survey of cars showed that the probability distribution of A is as follows. X 2 3 4 5 P(x) 0.65 0.10 0.12 0.03 0.10 Send data to Excel Part 1 of 7 (a) Find P (4). P (4) = X 5(b) Find P(less than or equal to 2). P(less than or equal to 2) = X 5 Part 3 of 7 (c) Find the probability that a car has only one occupant. The probability that a car has only one occupant is X 5(d) Find the probability that a car has fewer than four occupants. The probability that a car has fewer than four occupants is X 5 Part 5 of 7 (e) Compute the mean J . Round the answer to two decimal places. The mean H is X 5(1') Compute the standard deviation ox. Round the standard deviation to three decimal places. The slandard deviation 61 is D . (9} To save energy. a goal is set to have the mean number of occupants be at least two per car. Has this goal been met? Since the computed mean number of occupants per car is only [3 , then this goal to have the mean number of occupants to be at least two per car (Choose one) 7 been met. has has not
