Question: Streams. Researchers in the Adirondack Mountains collect data on a random sample of streams each year. One of the variables recorded is the substrate of the streams-the type of soil and rock over which they flow. The researchers found that 69 of the 172 sampled streams had a substrate of shale. Construct a 95% confidence interval for the proportion of Adirondack streams with a shale substrate. Clearly interpret your interval in context.
