Let X be a discrete random variable. If Pr(X<10) = 1/8, and Pr(X<=10) = 3/16, then what is Pr(X=10)?

SAT math scores are normally distributed with μ=500,σ=100.  What is the probability a randomly selected score is less than 620 points  What score separates the highest 1% of scores from the rest?

Prob-1 Probability that cars have been assembled in a particular plant as follows: P(plant1) =20%, P(plant2)=24%, P(plant3)=25%, P(plant4)=31%. Total number of cars manufactured by all plants: 1.2 million/year. Number of cars of no warranty claims manufactured by plant1: 223200/year. Compute the warranty claim rate of the cars assembled in plant1? C: warranty Claim rate NC: No warranty claim rate= 1- C P1 20% Total Cars Manufactured C = P2 NC 24% P3 P4 .% 25% 31% C NC C C Z NC .NC

For each probability and percentile problem, draw the picture.A random number generator picks a number from 1 to 8 in a uniform manner.   Part (h) P(X > 5 | X > 3) =         (Enter an exact number as an integer, fraction, or decimal.)   Part (i) Find the 60th percentile. (Round your answer to one decimal place.)

Tire pressure monitoring systems (TPMS) warn the driver when the tire pressure of the vehicle is 26% below the target pressure. Suppose the target tire pressure of a certain car is 28 psi (pounds per square inch.) (a) At what psi will the TPMS trigger a warning for this car? (Round your answer to 2 decimal place.) When the tire pressure is (Click to select): psi. (b) Suppose tire pressure is a normally distributed random variable with a standard deviation equal to 3 psi. If the car's average tire pressure is on target, what is the probability that the TPMS will trigger a warning? (Round your answer to 4 decimal places.) Probability (c) The manufacturer's recommended caorrect inflation range is 26 psi to 30 psi. Assume the tires' average psi is on target. If a tire on the car is inspected at random, what is the probability that the tire's inflation is within the recommended range? (Round your intermediate calculations and final answer to 4 decimal places.) Probability
