An article suggests that substrate concentration (mg/cm3) of influent to a reactor is normally distributed with μ = 0.30 and σ = 0.08. (Round your answers to four decimal places.) (a) What is the probability that the concentration exceeds 0.50? (b) What is the probability that the concentration is at most 0.20? (c) How would you characterize the largest 5% of all concentration values? The largest 5% of all concentration values are above mg/cm3. You may need to use the appropriate...

1. The following bell curves belong to probability distributions of three dif- ferent phenomena in nature. Which curve has the largest standard deviation o? 2. The article "Reliability of Domestic-Waste Biofilm Reactors" (J. of Envir. Engr., 1995: 785-790) suggests that substrate concentration of influent to a reactor is normally distributed with = 0.3 and 0 = 0.06. a. What is the probability that the concentration exceeds 25? b. What is the probability that the concentration is at most .10?
An article suggests the lognormal distribution as a model for SO2 concentration above a certain forest. Suppose the parameter values are μ = 2.1 and σ = 1.1. (a) What are the mean value and standard deviation of concentration? (Round your answers to three decimal places.) mean standard deviation (b) What is the probability that concentration is at most 10? Between 5 and 10? (Round your answers to four decimal places.) at most 10 between 5 and 10
Example 8.4 An automobile model is known to sustain no visible damage 25% of the time in 10-mph crash tests. A modified bumper design has been proposed in an effort to increase this percentage. Let p denote the proportion of all 10-mph crashes with this new bumper that result in no visible damage. The hypotheses to be tested are Ho: P = 0.25 (no improvement) versus Ha: p ? ? 0.25. The test will be based on an experiment involving...
