According to the USGS, the daily water consumption for a US household has an unknown distribution with a mean of 127 gallons and a standard deviation of 6.6 gallons. Let X be the daily water consumption for a randomly selected a US household and let S be the total daily water consumption for a random sample of size 49. 1. Describe the probability distribution of X and state its parameters μ and σ: X ~ Select an answer ( μ = σπ and find the probability that the daily water consumption for a randomly selected a US household is between 115 and 115 gallons. 2. Use the Central Limit Theorem Select an answer (Round the answer to 4 decimal places) to describe the probability distribution of S and state its parameters us and σs: (Round the answers to 1 decimal place) S~Select an answer(μs = ,σς and find the probability that the total daily water consumption for a sample of 49 randomly selected US households is less than 6268 gallons. (Round the answer to 4 decimal places)
