oday, the waves are crashing onto the beach every 5.9 seconds. The times from when a person arrives at the shoreline until a crashing wave is observed follows a Uniform distribution from 0 to 5.9 seconds. Round to 4 decimal places where possible. The mean of this distribution is ______ The standard deviation is ______ The probability that wave will crash onto the beach exactly 5.4 seconds after the person arrives is P(x = 5.4) = ______ The probability that the wave will crash onto the beach between 1 and 4.1 seconds after the person arrives is P(1 < x < 4.1) = _______ The probability that it will take longer than 4.48 seconds for the wave to crash onto the beach after the person arrives is P(x ≥ 4.48) = ________ Find the maximum for the lower quartile. ______ seconds.
