Do you carpool? Let X 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 X is as follows. Part: 0/7 Part 1 of 7 (a) Find P(4), P(4)- Part: 1/7 Part 2 of 7 20 1 2 3 4 5 P(x) 0.68 0.12 0.11 0.03 0.06 Send data to Excel X (b) Find P(Less than or equal to 2). P (Less than or equal to 2) 0,12 X Part: 2/7 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 0.68 Part: 3/7 Part 4 of 7 (d) Find the probability that a car has fewer than two occupants. X The probablety that a car has fewer than two occupants is X Part: 4/7 Part 5 of 7 (e) Compute the mean Hr Pr 1.67 x Parti 5/7 Part 6 of 7 (1) Compute the standard deviation a. Round the answer to three decimal places 1.20 Parti 6/7 Part 7 of 7 (9) To save energy, a geal is set to have the mean number of occupants to be at least two per car. Has this goal been root? Since the computed mean number of occupants per car la , thea the goal to have the mean number of occupants to Do
