The average weekly income of a supervisor on duty in the glass industry has a normal distribution, with a mean of $ 1,000 and a standard deviation of $ 100. That is, μ = $ 1,000 and σ = $ 100. What is the probability to select a supervisor whose weekly income ranges from $ 1,000 to $ 1,100? This question is expressed with Probability notation as follows: P ($ 1,000 <weekly income <$ 1,100).

Today, the waves are crashing onto the beach every 4.1 seconds. The times from when a person arrives at the shoreline until a crashing wave is observed follows a Uniform distribution from 0 to 4.1 seconds. Round to 4 decimal places where possible. a. The mean of this distribution is b. The standard deviation is C. The probability that wave will crash onto the beach exactly 2.8 seconds after the person arrives is P(x = 2.8) = d. The probability that the wave will crash onto the beach between 0.4 and 1.9 seconds after the person arrives is P(0.4 0.82) = f. Suppose that the person has already been standing at the shoreline for 0.5 seconds without a wave crashing in. Find the probability that it will take between 1 and 4 seconds for the wave to crash onto the shoreline. g. 26% of the time a person will wait at least how long before the wave crashes in? seconds. h.
