An article suggests the lognormal distribution as a model for \( SO_2 \) concentration above a certain forest. Suppose the parameter values are \( \mu = 1.7 \) and \( \sigma = 1.1 \). --- ### (a) What are the mean value and standard deviation of concentration? **(Round your answers to three decimal places.)** - **Mean**: \( 10.024 \) ✔ - **Standard deviation**: \( 15.378 \) ✔ --- ### (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**: \( 0.7088 \) ✔ - **Between 5 and 10**: \( 0.4655 \) ✘ --- You may need to use the appropriate table in the [Appendix of Tables](#) to answer this question.
