Streams Researchers in the Adirondack Mountainscollect data on a random sample of streams each year.One of the variables recorded is the substrate of thestreams—the type of soil and rock over which they flow.The researchers found that 69 of the 172 sampled streamshad a substrate of shale. Construct a 95% confidenceinterval for the proportion of Adirondack streams with ashale substrate. Clearly interpret your interval in context.
