The round off errors when measuring the distance that a long jumper has jumped is uniformly distributed between 0 and 4.7 mm. Round values to 4 decimal places when possible.

1. The mean of this distribution is


2. The standard deviation is


3. The probability that the round off error for a jumper's distance is exactly 1.1 is P(x = 1.1) =


4. The probability that the round off error for the distance that a long jumper has jumped is between 0 and 4.7 mm is P(0.2 < x="">< 0.9)="">


5. The probability that the jump's round off error is greater than 1.04 is P(x > 1.04) =


6. P(x > 2.8 | x > 0.6) =


7. Find the 81st percentile.


8. Find the maximum for the lower quartile.
