Question
Assume the weight of a randomly chosen American passenger car is a uniformly distributed random variable ranging from 1,557 pounds to 4,665 pounds.
What is the probability that a vehicle will weigh less than 1,946 pounds? (Round your answer to 4 decimal places.)
What is the probability that a vehicle will weigh more than 4,455 pounds? (Round your answer to 4 decimal places.)
What is the probability that a vehicle will weigh between 1,946 and 4,455 pounds? (Round your answer to 4 decimal places.)
Assume the weight of a randomly chosen American passenger car is a uniformly distributed random variable ranging from 1,557 pounds to 4,665 pounds.
Explanation / Answer
(c) P(X<1,946) = (1946-1557)/(4665-1557 ) =0.1252
---------------------------------------------------------------------------------------------------------
(d) P(X>4455 ) = (4665-4455)/(4665-1557 ) =0.0676
---------------------------------------------------------------------------------------------------------
(e) P(1946 <X< 4455) =(4455-1946)/(4665-1557 ) =0.8073
