A researcher took water samples in a forest with a stream running through it. The samples were collected over the course of a year. Some samples were collected from the stream itself (called the “surface” group), some were groundwater samples collected from organic soils (called the “organic” group), and some were groundwater samples collected from mineral soils (called the “mineral” group). Each sample was analyzed for the concentration of dissolved organic carbon (mg/l). The researcher wants to test the claim...

Samples of rejuvenated mitochondria are mutated (defective) in 2% of cases. Suppose 14 samples are studied, and they can be considered to be independent for mutation. Determine the following probabilities. (a) No samples are mutated. (b) At most one sample is mutated. (c) More than half the samples are mutated. Round your answers to two decimal places (e.g. 98.76). (a) The probability is (b) The probability is (c) The probability is

Gold miners in Alaska have found, on average, 12 ounces of gold per 1000 tons of dirt excavated with a standard deviation of 3 ounces. Assume the amount of gold found per 1000 tons of dirt is normally distributed. a) What is the probability the miners find less than 12 ounces of gold in the next 1000 tons of dirt excavated? b) What is the probability the miners find less than 6 ounces of gold in the next 1000 tons...
