a. b. c. The mean of this distribution is D The standard deviation is D The probability that wave will crash onto the beach exactly 1.2 seconds after the person arrives is P(x = 1.2) = The probability that the wave will crash onto the beach between 1.2 and 1.5 seconds after the person arrives is P(1.2 2.32) = C] Suppose that the person has already been standing at the shoreline for 0.8 seconds without a wave crashing in. Find the probability that it will take between 3.3 and 3.7 seconds for the wave to crash onto the shoreline. C] 60% of the time a person will wait at least how long before the wave crashes in? D seconds. Find the maximum for the lower quartile. D seconds
