The round off errors when measuring the distance that a long jumper has jumped is uniformly distributed between 0 and 6 mm. Round values to 4 decimal places when possible. a. The mean of this distribution is 3 b. The standard deviation is 1.7321 c. The probability that the round off error for a jumper's distance is exactly 2.7 is P(x = 2.7) = d. The probability that the round off error for the distance that a long jumper has jumped is between 0 and 6 mm is P(1.9 1.5) = f. P(x > 4.7 | x > 1.6) = g. Find the 47th percentile. h. Find the minimum for the upper quartile.
